These are all 0g, the glass/metal/stone ones have been professionally sanitized in a pressure sanitizer, I soaked the acrylic ones in alcohol then tea tree oil. O-rings available at request (free). These are all for sale, $8 OBO each pair, shipping is a dollar.
I'll take paypal, if you want multiple sets I'll give you a discount.
