Query: Doesn't stick

I had colorforms when I was a kid back in the 60s, and I thought it would be perfect for my three-year-old. Unfortunately, the stickers didn't stick--not at all.My wife and I thought this was a fluke and bought a different Colorforms--Dora the Explorer--and the pieces in that box also didn't stick.How does the maker of Colorforms--University Games Corporation--stay in business?
