standard plastic sheeting, sometimes used under shingles on housing now. It's no more than 1cm thick. they have it on the box at blue. its perfect for curved boxes because it can be easily shaped. Personally I'm all about this countertop material we have at my house. it a decent slide when try, and ridiculously cool when wet. plus it can come in a variety of colours. I'm thinking of making a small flat bar rail out of wood and capping it with some camo countertop.
