"As a semi-professional artist, I find this cups to be helpful in a number of ways, not only for small amounts of paint both straight and for mixing, but for holding small embellishments, I also use them for holding glue when attaching small items. They hold their shape well and even stay in shape when left covered on my work table for several days. I would strongly recommend them to anyone who paints. It is much easier to throw away a paper cup than wash a pallet or use copious amounts of foil, etc."
