Review on Jigsaw Puzzle Glue Mat Sticks by Don Merritt

These puzzle blocks are not as sticky or strong as others I have used. They don't look like cardboard/paper with glue. They are more like laminate, a material similar to transparent tape. They are more difficult for me to put on as they are thin, like a ribbon. So you need to glue on one side and then gradually glue to the end of the sheet. I also don't feel like the glue is very sticky - I suppose it depends on your preferences and whether you want it to be more or less sticky. The other backings I use are more like cardboard/hard paper with glue and I like them better. Once I have these inserts in place, I can fully assemble the puzzle and be sure it won't fall apart.
