Pyrocreations.com has removed the 1/16 " fuse from their web site.
However, Steve from Pyrocreations tells me that at this time he actually still has 1/16 " fuse in stock.
He told me that if you want real 1/16" fuse, to order 2.2 mm fuse and then tell him in an e-mail that you really want 1/16" fuse.
I would suggest an e-mail to Steve at pyrocreations first, to make sure he still has some 1/16" in stock, and then place the order and tell him what you really want.
