- Hiili – fully carbon-black birch with the wood grain still visible. A unique black wooden phone case.
- Lumi – a light wooden phone case made from natural birch. Clean, calm, and authentic.
- Rosa – warm pink birch where the wood’s natural structure remains visible.
Birch feels different in your hand than plastic: warm, light, a bit like the spine of a hardcover book. Every wooden phone case is one of a kind – the grain pattern is the tree’s fingerprint.
Structure and protection
+ Textured edge profile – birch has grip built in. The wooden phone case stays in your hand even with gloves on, and won’t slide off the table like glossy plastic.
+ Raised edge protects the screen – you can place your phone on the table without the display touching the surface. Read more about protection →
+ Raised camera frame – the lens doesn’t touch the table. The camera stays better protected from everyday scratches and bumps.
+ Thin and lightweight design – birch won’t bulk up your phone in your pocket, but in your hand it feels in a whole different league than a plastic case.
+ MagSafe compatibility available – wireless charging, magnetic stands, finger grips, and wallets work securely when you choose the MagSafe version.
+ Laser engraving, your own image or logo – name, initials, company logo, symbol, or your own image. Live preview shows the result before you order. See the design guide →
Not from stock. Nordic, made to order.
Black birch. Not black plastic.
Each Hiilikoivu phone case is made to order in the Nordics from Nordic birch. Lastu’s own dyeing process takes the black deep into the wood, while leaving the grain visible – that’s why every Case is black in a different way. This is a phone case that looks black but feels like wood. People usually notice the difference when someone asks to hold it. See how the Case are made in Northern Finland →
Surface Fully charcoal black from Lastu’s own dyeing process. The grain remains visible beneath the black – in the light it appears, in the dim it disappears. Every black wooden phone case is one of a kind.
Lacquer Lightweight, non-toxic, water- and dirt-repellent finish. The wood feel remains – not slippery, not cold, and not the fingerprint magnet black Case usually are.
MagSafe Available on the product page for many phone models. Do you need a MagSafe phone case?
Engraving Engraving reveals the light tone of birch beneath the black – like brushing away ash. A name, logo, coordinates, or symbol stands out in crisp contrast.

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!
