I'm shocked at how much it actually holds. I keep all my diamond painting supplies in this bag except drill bits and there is room for more. My lightweight A3 rubber fits widthways but sticks out a few inches at the top. It does not bother me.
Pros
DIMENSIONS - 13 x 4 x 14.6 in. Compatible with A4 size LED panels and diamond painting tools. Perfect gift for diamond artists, beginners or diamond painting masters.
