Sorry this is a delayed response, but i used to work in a donut shop and they have air tight buckets that fillings come in. If you go to a donut shop and ask for one some may give it to you for free and others may charge a few dollars. just was and rinse very good with bleach and soap. I use them for my ferrets and they work great. Merri, Sarah and Allie-gator [Posted in FML issue 2043]
