Stirring the paint is very important in painting. However, simply shaking the paint or using color mixing sticks tends to leave pigments in the corners. Vic Hobby has introduced a new item to assist in this process. By adding an appropriate amount of this product (manufacturer's recommendation is two) to a Vic Color container and shaking it, you can stir it thoroughly to the corners of the container. This product can be used for both regular Vic Colors and Set Colors. Rust-resistant stainless steel balls are used. 50 pieces are included.
