versatile but watch out for short springs that come loose [SEP] these work as advertised big enough to fit my large fingertips without hurting them they are a hard clear plastic with a metal rod and a metal spring make sure when you get yours to check the back end to see if the springs are aligned in the slots if not slide them with a fingernail or tool until they go into the slot the batch that i received have metal springs that barely make it into the slot which makes the spring pop out if i open the clips all the way if the springs were long enough these would get a star rating from me as they are i cannot recommend them however i do like that they come individually wrapped so they could be gifted in sets of or and the receiver would know the clips are unused
