My first experience with these pins was when they came in the Christmas box. I loved how they smoothly slid into fabric. I bought more when they were on sale. As I use them however, I find that a few have bent as I tried to push them through several layers and the flat head came off of a couple, too. I’ll just have two pin cushions: One for these which glide through fabric and my ‘old’ pins which are more durable when pinning several layers.
