One gram of 2.5mm silver crimp tubes. Packaging does not indicate if these are silver, silver plate or silver tone. I am listing them as silver tone just to be conservative. Beadalon Crimp beads have an ultra smooth, brilliant finish which protects the beading material and also adds a touch of elegance. These beads are easy to crimp and can be rounded off using a crimper tool. They can be used to secure the start and finish of the strand and give your designs a more professional appearance.
