Handmade Flower Epoxy Resin Coaster- $12 for 1 Coaster Coasters size: 3.5 in x 3.9in Hi, please understand that each art piece may have its own imperfections which makes it unique. No one piece will be identical to another. This ensures the art pieces are handmade and detailed are uniquely placed. (Every Flower Blooms Differently) My resin arts are made fresh with each order ensuring top quality, scratch, stain, and yellowing resistance, and overall excellence. However, I recommend allowing 30 days for compete curing of the resin before putting it into use. Do not place items hotter than 125°F on the cured surface or it may become distorted and discolored. Thank you for your support. All Sales are Final.
