They sent me a sample pack including 2 @ 18mm and the rest 4 mm but ignored my colour request. The 18 mm is not especially attractive so will probably use it for bushes and cones. I guess I got the pack because I used the company details on the request.Yes Alan, there is a link to their site somewhere (search Parapan) you can choose what colour samples you want and thickness,
18mm or 4mm, out of the 6 I ordered, I only got 1 x 18mm the rest 4mm.
There are some nice colours to choose from.
