FREE: Keychain

Just some advice on postage, if you place it loose in a plain white envelope, two things could happen. One, if it's machined, which it will be with one stamp, it very likely will get torn/ripped and probably push the keychain out. I've received SO many empty envelopes because people just dropped loose keychains in a plain white envelope & it got machined. It's best to wrap it in something... paper, tissue, something, and tape it to something firm like cardboard or card-stock, something that will take most of the envelope space, so it can't easily fall out. Or use a bubble mailer to be totally safe. Even in that, if it's still one ounce, it's only $.88.
Two, the jump ring that connects the split ring to the heart could easily cause it to be thicker than 1/4" thick... or even just being 'rigid', it most likely will be more than one stamp.... either $.64 for just a rigid 1 ounce, or $.88 for being too thick. So be sure to have it checked at the post office, or it will arrive postage due, or come back to you.
