can t open with one hand [SEP] i use to buy these for a piece at the swap meet so when they started going up in price i thought i d buy a larger quantity for a better value they look really good in terms of a nice quality plastic and just the size i needed the problem is the spring is too tight and i can open it with one hand thumb and finger doesn t work and a full grip in the palm with the thumb doesn t work if i open with two hands i only have one hbd to work with twisting my hair up so i think these will have to be returned
