"I am overall very happy with ArtBeads and have loved all their products; unfortunately, this extender disappointed me. The chain links are too small (around 2.5 - 3mm). Unless you are using a very small lobster clasp, the lack of big links makes it harder to hook the clasp onto the extender. I typically use the 11mm lobster clasp, and while it does fit through the link, it barely does. I do love the Stardust Bead on the end though."3 of 3 people found this review helpful.
