Adam Hall Plastazote LD29 10 mm

This stuff is ideal inner lining and protection for home built road cases. It's firm enough to withstand the usual bumping around that cases have to put up with, but also a little spongy so that it cushions the equipment well. It comes with a peel back sticky reverse side, so it's very easy to cut to size and stick firmly into place without messing around with glue. One sheet of 2x1 meters will do about 2 medium sized keyboard cases. Great stuff!
