I ordered it with two 32 inch chains, one for my sister and one for me. But you can also put both on one necklace. The necklace is big enough so you can still connect them together when they're on one necklace. I'm very happy with the fast shipment and nice packaging. The price for the product is really good. It looks exactly like the picture and they're not too small. I'll be ordering science jewelry here again!!
