Good quality, very sturdy
These are a thick, sturdy plastic and will keep your borders, stickers, etc, safe from damage. Because of the thickness, they are also slightly opaque so it isn't easy to see through them. I would love to see these in a slightly smaller size, like 3 x 13, to store narrower borders for scrapbooking. And it would be nice if they were more clear so it is really easy to see what is inside, but not if that would compromise the quality.
