I like the idea of these nylon protectors for your round nose pliers, however, there is a significant design fault in that once they are placed on the pliers, the tip of the nose cannot meet so this renders the pliers ineffective for wire wrapping, in particular if you want to make a small, tight loop as is often required in jewellery making. This may be due to the bottom (widest part of the nylon jaws) being too thick and so the top/nose of the pliers do not meet.
