The dollar I'm offering for shipping would even cover the whole shipping, we'd kinda be splitting it. These things wouldn't hold up in the mail if I didn't package them well. USPS is rough with packages. But I'll say if the bid gets over 50 I'll offer free shipping.
If I had the materials still to make more I would sell them for about $3 for the set. It doesn't take much to make them. I just got rid of all of my jewelry making supplies so I wouldn't be able to make you a pair. Good luck.
