I was having a hard time finding 4-strand pure copper slide clasps. Others had 2-strand, 3-strand and 5-strand clasps, but not 4-strand. I thought that was pretty odd, but I refused to give up hope.
I was looking at Auntiesbeads website and lo and behold, they had just what I had been looking for and at a reasonable price. I was sold and bought several so as not to run out.
Thanks to Auntiesbeads I have completed a copper wire-woven 4-strand bracelet that turned out very nice.
