Black tacky non-slip matting

I picked up some rolls of black non slip matting off Amazon, inspired by the coverings of my late Mother's tea trays. If it stopped teacups and plates of cake from sliding around then there is a fair chance it ought to work with figures in their storage boxes and stop them from sliding all over the place, and if it works I will be a big fan of all things black, rubbery and tacky ;o). £1.99 a roll I think.
