Not enough spots for sockets need 22 24 mm space added

They work well and fit perfectly in my tool chest, great product

Love these things .. I go to a lot of estate sales and get random sockets so this helped me organize the ones that are the best into a complete set instead of looking in a bucket of 300 sockets for the one I need
