Bought a bunch of these. I would rate 5 stars if i can figure out how to use these refill on my "Command Traditional Plastic Hooks Value Pack, Medium, Brushed Nickel" ?!!! I took down the strips and holders to move the drapes to another window. I lost the instructions and for the life of me, i cant imagine how the boxes of medium size refills can fit and work on the existing decorative metallic holders i saved??
