I think I'll let the pic do the talking first... I updated this, as a lot of stuff went. If you're interested in any of these, PM me and tell me which ("top row, third from left", etc) Shipping for the little envelope was always $2 at USPS, so unless you buy all of them, shipping is a flat rate $2 to the USA. PM if elsewhere. Any knob in this pic, $3 each, unless you buy multiples. And that's a flexible policy, too! Paypal only.
