KANSI — MacBook back cover made from authentic materials
MacBook back cover made with genuine natural materials: birch, carbon fiber, and M05 fabric. No plastic. No industrial coating. No two alike.
Lastu has been making MacBook cases since 2011 — first in Finland. After a multi-year break, these much-requested products are finally back, refreshed and improved. KANSI fits all current MacBook Air and MacBook Pro models.
Why KANSI?
Authentic material
Every KANSI is made from real material — birch veneer, carbon fiber, or M05 fabric. No laminate, no PVC. Wood lives, breathes, and develops its own patina. Your MacBook will eventually look unique — because it is.
Protects from scratches
The MacBook’s aluminum body scratches easily. KANSI covers the entire flat surface of the back cover and protects it from everyday bumps, sliding across desks, and rubbing in your bag — invisibly, without extra bulk.
Easy to install — easy to remove
KANSI attaches with 3M adhesive to the flat back cover. Installation takes less than a minute. When you want to remove it, it comes off cleanly and leaves no marks on the cover. No risk. No commitment against your will.
Water-repellent treatment
All KANSI materials are treated to be water-repellent — even wood. Coffee splashes and light moisture won’t damage the surface. Non-toxic treatment, safe to use.
Personalize with your own engraving
For an extra €5, you can add laser engraving: your logo, image, text, or a choice from Lastu’s ready-made illustration selection. Engravings are cut with laser precision directly into the material you choose.
Nordic craftsmanship — no mass production
Every CASE is made to order in Oulu. No stock, no mass production, no two exactly alike. By buying from Lastu, you support Nordic craftsmanship and local production.
2011
History
Lastu started making MacBook back covers in 2011 — the first company in Finland. Back then, every cover was sanded and finished by hand from birch veneer. The products built a loyal fan base, but the lineup was gradually phased out in favor of phone cases.
Over the years, the requests never stopped. Now KANSI is back — with a broader lineup, better materials, and designed for the new generations of MacBook. Same attitude. Same craftsmanship. Nordic-made.
