There are many types of crimp ends and tubes, but all of them are used to neatly finish necklaces, bracelets or earrings, and also to create a space for attaching a clasp, jumpring or other jewelry findings. This model is designed for soldering close link chains. It measures 1 x 5.3 mm, so will be perfect for subtle chains with a thickness of 1 mm and thinner. This flat chain end needs to be lightly crimped around the end of the chain and then soldered together. Its shape allows attaching jumpring, as the connector with other jewelry parts. In our offer, you will also find other widths of the ends for soldering, so you can match them perfectly to the size and type of the chain used in your jewelry.
