We've featured the bamboo, retro-style Lexon Safe radio previously but the products in the range go beyond that piece to include clocks, flashlights and this calculator.
Designed by Elise Berthier and Pierre Garner, you can tell the calculator comes from the same design family as the radio. Its chunky keys and rounded edges give it that retro look while its got eco credentials too: solar powered and made from natural bamboo with a casing from corn starch bio-plastic.
And the price for the calculator? It adds up to £21.40.
