The innovative design of our exclusive divided paint cup lets you offer 2 colors at once: one on each side of the cup's center divider. The holes in the no-spill inner lid guide paintbrushes into the cup and help prevent drips. And the airtight outer lid keeps paint from drying out while stored. Perfect for projects that only require 2 colors, as well as for doubling the number of color choices at the easel. 3 5/8"H x 2 1/2" in diameter at base. Patent 7,090,072 B 1. Each cup holds up to 8 oz.
