Update Hello. My shop remains open, but orders will resume on 7th Sept.This is a beautiful set of 4 small wine glass coasters that peice together to form a stunning agate style appearance, however this set has a flaw so being sold at a discounted price of 10, usually 20. The flaw is they have some micro bubbles visible. These are made from resin & are not heat resistant, therefore for cold drinks only. After care advice. To clean your coasters use a slightly damp microfiber cloth. Do not use any product, as they may effect the shine. Keep out of direct sunlight. (Not daylight, hot sunlight). See my other luxury resin items, such as trays, wine butlers. Thank you for looking. Rach x Discounted Item With Flaw Luxury Handmade Home Decor Agate Geode Crystal Gem Coasters Gold Leaf
