I made this one... the top and bottom squares are 8 x 8 and the sides are 3 inches tall. It's huge. It doesn't move and doesn't get lost. I also like it because it gives me a spot to place extra bobbins, tools, thread etc and I can carry it from place to place if need be. There are 100 button head pins in it in the photo plus other pins and needles that I use frequently and other stuff that I like to keep close by when I am working.
