Safety pin with removable catch

Does anyone know where I can get silver safety pins with removable catches other than Rings & Things?  They are temporarily out of stock and I'm wonder if any retail shop or web site sells them.  They are very hard to find.  I'd appreciate it if anyone can guide me in the right direction.

These are hard to find, and we're not sure when they'll be back in stock.
If you know of an alternate source where Dina can find them, don't be afraid to post.

As soon as I hear anything concrete (or anything vague for that matter) about when we'll see these again, I'll post it here.

still looking for these.  if anyone has found a source please email me @ sgfchicago@aol.com.

thanks!

We will get the 30-652-1 again, but I don't have a solid date yet.  I will continue to nag the vendor.
