My shaving mug is currently occupied with a soap puck so I needed a storage solution for a couple of pliable soaps I had but everything I was finding was much too big. I wanted something small that I could cover/seal and put away so I wouldn't have 3 open mugs sitting around and cluttering up the bathroom. I was at the Dollar Tree and found my solution in the baby section. They were selling a set of 5 snack cups with lids for, of course, a dollar! These things turned out to be just what I was looking for! To get an idea of their size, they are just slightly larger than the single serving fruit cups you'd get at the grocery store. I checked their capacity using water and they held about 1/2 a cup. I smushed a stick of Arko in one and would probably have enough room for a 2nd stick. I also had a slab of Cella from a board member and smushed that into the bottom of another cup. They stack nicely and don't take up much room. At 20¢ each and a variety of colors, you can't go wrong.
