These are 38mm from edge to edge, 50mm from corner to corner and about 4.5mm thick. I am not sure what the material is that these are made from, but it is stiff and light weight. The wood grain is like a laminate. These will come to you with protective peel off paper on both sides (see photo 3). Each piece has one side wood grain and the other side a spiral.
Faux wood grain and geometric spiral pendants charms. Jewelry supplies.
