These are Brass clasps that are powder coated - that means they will have touch marks where the color is not perfect. We do not guarantee you get a perfect coating on all clasps. That being said they are pretty well covered as you can tell by the pics - click the pics for a larger view.
Please Note: Most of these are 15mm. The stats for 15mm are as follows. 15x8mm with approx. 1.5mm hole - loop fits up to 16g (0.062", 1.6mm) but not all. The loops fits a max of 18g square wire. Clasp will hook onto up to 12g (2.5mm 0.1"). There is variation in this likely due to paint thickness.
JC-LC-SV12-PINK - 12x6mm with approx. 1.5mm hole - will fit up to 1.2mm wire (18g) - some fit 16g (0.062", 1.6mm) but not all. This is likely due to paint thickness.
