They really aren't needles, they are little sticky plastic tabs that help you thread the ribbon onto your paper. Very handy! if you haven't tried the sew ribbon products, you need to, very easy and a lot of fun, my 12 year old daughter and I tried them and now we are hooked...we are "sewing" on all our cards and layouts!
Since there are some needles include in the Sew Ribbon tool set that I purchase, thus this pack become surplus to certain extend. But still be nice tool for card making.
