Absorbent Wristbands Pink and Blue, Set of 2 Pairs 100% Polyester These wristbands fit snugly on your arms and absorb water that runs down from your wrists when washing your face, preventing your sleeves from getting wet and keeping the floor under the sink dry. They contain elastic, so they can be used by elementary school-aged children. They are especially recommended for children who are still short and tend to make a mess under the sink! For children in kindergarten or younger, they might be a little loose and not stay on the arm properly, possibly sliding down to the wrist. It depends on the child's size, so it's hard to say for sure... They are also convenient for doing water work such as washing dishes, as they can be used to hold your sleeves in place. I bought two sets of 2 pairs each so I could have spares, but I found that 2 pairs were enough, so I am selling the unused two pairs. During storage, some dust has adhered to the slightly peeled edges of the tape, but they are unused. (Photos 7-10 show the tape on the bag.) The ones taken out of the bag are my own personal items that I use. Please use them as a reference. They were originally 5 x 7.5cm when purchased, but after using and washing them, I feel like the width has stretched a little. They fit my arms perfectly in this state.
