The Green Tool DoubleUp chopping board from The Eva Solo is a two-part folding chopping board. The chopping board consists of two pieces that are easily attached together with magnets, which allows you to adjust the size as needed or use the surfaces separately. The magnets hold the pieces of the chopping board in place so you can angle it to collect the vegetables and pour them into whatever pot you are using so you don't lose any. When the chopping board is not in use, you can attach the surfaces together to save space and lean the chopping board against the wall.
