Brad Walsh's Knockers

Been cooing over these all morning. (And over cats on gumtree, but that's another story...) I want to stick one on a really long chain, even though I don't wear pendants. Anyway here's Brad Walsh's Etsy shop, he has nice turquoise glass ones too (among others) but what I really want is a turquoise version of the ones above. It looks like you can from his top picture but apparently not.

("More Money Please" isn't that appropriate a tag, I know, but I just lost my job so budgets have had to be cut *sob*)
