TERWA – wooden tar birch phone cases & cases
iPhone, Samsung, OnePlus, Pixel, Realme, Nothing – dark brown, engravable
The campfire has smoldered through the night. Mist rises from the lake, the coffee pot starts to hiss, and the air carries that smoky, resinous scent you won’t find at the fragrance counter. TERWA is a handmade wooden phone case made from tar birch – dark brown and real, and it smells exactly like that morning. You pick up your phone about 56 times a day; here’s a Case that gives those moments something extra. The wood grain lives on the surface like growth rings in a stump, and no two are alike. Fits iPhone 17, 16, 15, 14, 13, Samsung Galaxy, OnePlus, Google Pixel, Realme and Nothing models. Add MagSafe or engrave a name and create your own TERWA Case.
In the wilds of Kainuu, tar pits smoked for weeks, tar boats came down the river to Oulu, and the whole city smelled of it. The same substance kept sailing ship ropes together across the Atlantic. Lastu was born in that city. TERWA is that tradition in modern form: a phone case treated with the same stuff – just on a slightly smaller scale.
Material: tar birch – smoke and grain
Shade & surface
Tar birch
- Tar birch – dark brown like a coffee pot that’s been sitting by the campfire, with the grain showing through. Every wooden phone case is one of a kind.
- The tar treatment repels water splashes – no stickiness and no staining on your hands. Morning dew, a rain shower and fishy hands are fine. Swimming is not.
- A subtle, genuine tar scent, not a fragrance. Strongest during the first weeks – when it takes you to a smoke sauna bench and a September lakeside rock – then settles into something only you know is there.

Structure and protection
+ Textured edge profile – the tar surface adds natural grip. The wooden phone case stays firmly in your hand and won’t slip.
+ Raised edge protects the screen – you can place your phone on the table without the screen touching it. Drop protection test →
+ Raised camera frame – the lens stays lifted, not in table dust. Your camera stays clear.
+ Thin and light. Birch is naturally lighter than most plastic phone cases – no unnecessary bulk.
+ MagSafe-compatible available – wireless charging and magnetic accessories work at full power. MagSafe vs regular Case →
+ Engraving – moose, coordinates, symbol, Lion of Finland or a name. Live preview shows the result before you order. See the design guide →

Frequently asked questions
What is a dark wooden phone case – recommendation?
TERWA is made from Nordic tar-treated birch, giving the wood a unique dark blue-brown tone and a subtle natural scent. No paint, no print. Every phone case is different thanks to the material. MagSafe-compatible available.
What does tarred birch mean — isn’t it sticky?
Silver birch is a Nordic wood whose surface has absorbed tar during treatment. It gives the wood a deep brownish-blue tone and a subtle pine scent. The finish is not sticky – the TERWA phone case is smooth and pleasant to hold.
Would TERWA make a good gift for a nature lover or cabin person?
Absolutely. Tar is part of Finland’s cultural heritage — a familiar scent, a natural material. TERWA is a meaningful gift for anyone who loves the outdoors, the cabin life, or simply appreciates authentic Nordic character.
Can the TERWA phone case handle everyday use?
Yes. The surface is finished to stand up to everyday use — it repels moisture and splashes. Engraving or your own image can be added. MagSafe-compatible available. Made to order in Northern Finland.

Kun Lastu-kuoret saapuivat kotelossaan ja sen avasi, tuoksui terwa! Hieno elämys, ja kertoi siitä, että nyt ollaan aitojen asioiden ääressä. Sukujuuriin liittyy tervanpoltto,siksikin halusin kuoret juuuri teiltä. Kuoret ovat just sellaiset kuin ajattelinkin, personoitu kuvio passasi hyvin valmiiseen tuotteeseen. Toimitus kesti pidempään mitä luvattiin, mutta se vain vahvistaa "käsityöläisleimaa". Kiva ostaa kotimaiselta. Tehkääpä vielä video puun matkasta metsästä kuoreksi, olisi kiinnostavaa seurata koko ketju terwauksineen kaikkineen. Kiitos ja terveisiä tyytyväiseltä käyttäjältä.
Very good
Todella hyvän tuntuinen ensin tervan tuoksu vähän yllätti mutta siihen tottui äkkiä👍🏻
Hienosti onnistunut kaiverrus. Ja tyylikäs kaiken kaikkiaan ja hyvä silikonisuoja myös.
Tämä on nyt kolmas lastu jonka ostan. Ensimmäisen ostin 13 vuotta sitten. Pidän kovasti
Kuori näyttää ja tuntuu hyvältä.
Puutöitä harrastavana se sopii kuin puukko tuppeen 😎
Kuori on tyylikäs ja kädelle mukavantuntuinen. Tervan tuoksu oli alkuun voimakas, ehkä turhankin voimakas, mutta se on maltillistunut viikossa eli sen suhteen ei ongelmaa. Puisen takapaneelin istuvuudessa yläreunassa on millin verran heittoa ja sen myötä syntyneeseen rakoon kertyy likaa.
Hyvältä näyttää 👍 en tiedä kuvittelenko vai oliko tässä alkuun jopa tervan tuoksua 🤩
Tuntuu erittäin hyvältä ja näyttää erittäin hyvältä, ei kertakaikkiaan mitään valittamista! 👍🏻
Aivan täysosuma!
Kuori vaikuttaa laadukkaalta ja kaiverruksen lisääminen on hieno idea! Olen hehkuttanut kuorta jo muille. Olisin hommannut tällaisen jo aiemmin. Jos vain olisin ollut ko. tuotteesta tietoinen.
Hieno kuori oman suomenpystykorvan kuvalla. Hyvä tervainen tuoksu. Nopea toimitus. Sopii uuteen Realmen puhelimeen kuin nenä päähän!
Fast delivery
Nämä kyseiset kuoret jo neljännet. Tulen vastaisuudessakin ostamaan.
It is a really high cuality case and I love it
Laadukkaan oloiset kuoret. Oma desing kaiverruskin on hyvä.Tilaan varmaan toistenkin👍🏼
Tämä oli toinen lastu puhelinkuoreni. Ensimmäinen palveli vuosia, mutta puhelimen vaihduttua vaihtui kuorikin. Tykkään todella paljon kuoresta ja lohi kaiverruksesta. Puhelinkuoren keskeltä vaakasuoraan menee juova, joka on hiukan kuprulla/sormilla tunnettavissa. Näkyy myös kuvassa, jonka olen ottanut hetki sen jälkeen kun avasin postipakettini. Juova on voinut tulla postituksessakin. Tämä on esteettinen haitta, kuori on itsessään ehjä. Se ei minua liikaa häiritse, mutta täydet 5 tähteä olisin antanut ilman juovaa.
Todella hyvä olen tyytyväinen, nopea toimitus oli myös. Suosittelen.
Kuori oli edelleen samaa taattua lastu laatua, kuori istuu hyvin ja suojaa hyvin.
4th or 5th Lastu case I've ordered so far. Now for Realme, earlier ones have been for 1+ and Samsung.
6/5
Tuotteen saamisessa meni todella kauan johtuen jostain tilausongelmasta, eikä saanut heti kunnon asiakaspalvelua että se olisi selvinnyt nopeasti ja nopeuttanut tuotteen saamista. Lopulta kun tuotteen sai n.1kk tuotteen tilaamisesta ja muutaman yhtetdenoton jälkeen oli se ihan hyvä ja toimiva suojakuori.
Erinomainen kuori!
On hyvä!
On komeat!!
Muutamat omalla kuvalla tilatut kuoret takana. Laadukkaat, hyvät. Vaikka kulumista ei näy,niin tekee mieli tilata uudestaa omalla kuvalla uudet kuoret 😊
Kauniit kuoret. Parasta on kotimaisuus!
Istuu moitteetta IPhone 13 malliin ja on tyylikkään näköinen
Laadukas kuori! Hieman pitkähkö toimitusaika.
Suojakuori on todella siisti ja sopii puhelimeen täydellisesti. Puhelin on nyt näköiseni 🙂... Ainoa miinus, että toimitus kesti kuukauden.
Hieno palvelu että voi tehdä omasta kuvasta custom kuvan kuoreen. Mutta magneettirinkula ei näy esikatselussa, joten se hieman häiritsee kuvan päällä. Sen voisitte lisätä esikatseluun mukaan, mikäli rinkula on tilauksella mukana, niin tietäisi asemoida kuvan optimaalisesti rinkelin kanssa. Eipä muuta, kovaa ajoa!
Jo toiset Lastun kuoret itselleni ja edelleen erittäin tyytyväinen laatuun ja ulkoasuun! :)
On niin hienot
hieno ammattitaidolla tehty kiitos
Kuoret on kyl hienot mutta toimitus 3.5 viikkoa ... ei ihan luvatussa ajassa
Todella tyylikkäät
Ihanat kuoret ❤️🌿
Juuri sellainen kun kerrottiin!
