I got these kitty ziplock baggies at the store and they are great for holding sandwiches or just random stuff! I put my sculpey clay in them! They come in two sizes, small and sandwich size. I got them at Safeway a while back. I don’t know if they still carry them, but here’s a tip: ask the store manager if they can get them! The store manager once told me that if I can’t find anything I want in the store, they could most likely order it!
