I've bought this transparent film to protect jigsaw puzzle I have recently completed and it Completely Fulfilled its purpose. I plan to stack few more of Those for my future puzzle "projects". Giving it 4 starts since I lacked one "useful" feature other similar products have. Back side of the film has to be removed did to expose adhesive side is compact and it has to be removed in one piece and than manipulating sticky film can be tricky. I prefer products where this "backside" Consists from smaller segment That can be separately removed. Very good price.
