Place a drop of glue or paint in the mini-cup. Then dip a toothpick or micro-brush to pick up and place a pin-point size dab of glue or single stroke of paint. The V-groove holds applicators and brushes of varying sizes and the weighted metal base prevents tip-over. Use with any glue or paint. Includes 250 toothpicks and 20 mini-cups. 1-1/4 inch diameter.
