So...I bought the wrong size...anyone who can use them, one of them or all of them...just email me & I'll figure out what shipping is (probably like $2 for all) and you can simply have them! They are new from Jeffers on 1/8/2010, still in plastic. Size 5/16" for Nigerian Dwarf and similar. Letters are B , F , & number 4 . Paid $2.19 each but I just don't want to keep them if I can't use them.
