Review on Precision Chrome Steel Bearing Balls by Devin Maselli

I buy and use small bottles of acrylic art and craft paint. Sometimes they get thick or just don't mix well. I add 4 or 5 of these little balls and mixing becomes easy; Simply shake the bottle up and down and the balls will mix the color easily. Saves money on painting. Balls can be washed and reused. Good buy for me.
