KELO – grey wooden phone cases & protective cases
tar-treated birch, deadwood-inspired shade | iPhone, Samsung, OnePlus, Pixel, Nothing
Kelo doesn’t grow in a hurry. And it doesn’t shout. KELO is a grey wooden phone case made from genuine Nordic birch – tar-treated, with a deadwood-like grey tone and the quiet of the northern forest in your hand. The shade deepens with use, and every case ages in its own way. Fits iPhone 17, 16, 15, 14, 13, Samsung Galaxy, OnePlus, Google Pixel, and Nothing models. We support the latest models right after launch – including iPhone 18 Pro and iPhone 18 Pro Max, Samsung Galaxy A57 and Galaxy A37, and Google Pixel 10a. Add MagSafe or engraving and make your KELO case yours.
If you’ve been looking for grey phone cases but don’t want cold aluminium or matte black plastic, Kelo is the third option: a grey born from standing still. Great for outdoor adventures and hiking too – built for everyday life, weather, and forest trails.
Material: Tar-treated birch – deadwood-inspired shade
- Greyish, dry tar treatment – like the surface of Nordic deadwood: more weathered and calmer than dark TERWA.
- Water-resistant natural product – no stickiness, no staining your hands. A dry, smoky scent that fades within weeks, but you’ll remember it.
- The wood grain shows through beneath the greyish surface – every wooden phone case is unique before anything is engraved on it.
Lastu was born in Oulu – a historic tar-trading city. KELO is a more understated interpretation of that heritage: drier, smokier, calmer. Read Lastu’s 15-year story →
Structure and protection
Not from stock. Made to order in the Nordics.
Kelo wood doesn’t rush. Neither does the KELO case.
Each KELO wood phone case is made to order from genuine Nordic birch in Oulu. The greyish tone comes from tar treatment and the wood’s own character – not industrially, not in a rush. Kelo wood stands in the forest for decades before it becomes kelo; we don’t quite go that far, but we don’t hurry either. See how the cases are made in Oulu →
MagSafe – snap and go
MagSafe compatibility available on the product page. The magnetic ring aligns the charger and accessories with a firm snap – one click and you’re good, no looking needed. Works at full power even out in nature when your battery is running low.
Pairs perfectly with these
- KRIP 2.0 MagSafe finger grip – slim, metal, also works as a finger grip and stand.
- KARB MagSafe wallet – room for up to 4 cards, no separate wallet needed for the trip.
