All our phone cases have genuine premium wood on the back (except Bifrost who has bamboo which is a type of grass). That makes every mobile case different from the next one because of their sustainable living material of real wood.
Think of it as unique fingerprints, every tree has its own unique annual rings and each cut from that tree has its own structure. Further more, all Lynx & Wood phone cases are carved with laser, resulting in a unique burn every time.
