Wristbands Material：Synthetic paper+PET******** Widely used in:Amusement park Wristband；for School to track people coming into the event；use these as name bands for classroom activities in group setting around their wrists；fundraising event wristbands；Wristbands for competition events, wristbands for party admission******** These were for School to track people coming into the event. They worked perfectly. Typical you need super human strength or a pair of scissors to cut them off. Once you stick the wrist on you can't adjust.********* Was good for the event we hosted and needed to be able to separate by sign/color so this really helps and was good for the one time event******** It was the nice bendy material - not hard plastic.******** The colors are vibrant. The adhesive stays well all day even through repeated handwashings. It can be used as name bands for who in group setting around their wrists. The material can be difficult to cut without very sharp scissors but that is simply because they are made to be tear resistant********** NOTE:******* Due to lighting effects, monitor's brightness, contrast settings etc, there could be some slight differences in the color tone of the pictures and the actual item.************ Please allow 1-2mm differs due to manual measurement.***** Check the detailed size of the Paper Wrist Straps if it fits your requirement before your purchase.
