Okay, so when I saw this product I had to have it; I had been struggling with my ever growing collection of ribbone for far too long!
It is a definate space saver, allows you easy visual access to all your ribbon at once, but, I caution anyone against filling it too full. Also, the best way to prevent tangles (which do happen-the more ribbon crammed in the more tangles) is to roll the ribbon around your fingers and then pull the end of the ribon from the CENTER of the roll through the hole!! I learned this the hard way! If your ribbon is longer than 2ft I recommend cutting it and pulling the two pieces through different holes, the longer the ribbon the more chance of tangles.
It is the best product I have found so far but it's not perfect....
