COLORWORK!!! When I do colorwork, I put my MC on one side, snap it in place and then I put my CC in the other side, snap it in place and voila! No tangles, no balls rolling across the room and I can change bags in a second by just moving my Oh Snap to the bag of the moment. This product is a GODSEND for doing colorwork and the best $19 I EVER spent!!
This is my second set in this color, great for projects. I use the small one to carry my necessities, scissors, crochet hook, stitch markers. It's easy to see what is where and slim line so easy to fit any size bag.
