easy to put into the hair comes with everything you need except pliers [SEP] i purchased these at a discount to try and review regardless this is my honest opinion these come as one big grouping rubber banded at the top together i marked this down a star for two reasons one i wish the color groupings were banded separately because trying to pick through and find just the one or ones you want only made us tangle the hair more and we had to stop and comb it to untangle it having them packaged separately instead as one big grouping would have saved us this trouble the other reason is because the colored crimp rings that come with them has a clear plastic or rubber ring inside them that must be removed for the extension to fit through the instructions said nothing about this and i was getting frustrated on the first one i did thinking it was not going to fit until i knocked that clear inside ring out of the way and then it worked fine neither of these are deal breakers for potentially buying these for my teen in the future again but they would be nice improvementsthis came with three colors of crimp beads which is nice for different colors of hair to help blend it into the roots everything you need is included except a pair of pliers which most households have in their basic or crafting tool kits i put one in my teenaged daughters hair to show her how to do it and after that she found it easy enough to do in both her and other peoples hair they go in and seem pretty durable since they are synthetic the color will last longer than a real dye job will the colors are bright and fun she has brushed and washed her hair multiple times without any issues with the extension
