Query: Stickers?

I bought three 4-packs of these dishes and was pleased to find they fit into my Cage Connection cages perfectly. I was not pleased to find that it took half the afternoon to get the large bar code stickers off the bottoms with razor blades and Goo-Gone. Whose idea is it to use adhesive on food dishes that requires toxic chemicals to remove it?
