I have been working with Art Resin for the past 4-5 years. I have tested many different brands by now but none really compare. Some yellowed in a year, some were hard and unpredictable to work with, some left striation marks on my top layer, and others smelled harsh and made my nose and eyes water. I have never had this issue with Art Resin. It has a stable formula with predictable behavior, and it's very easy to work with. It's also heat-resistant, non-toxic and food safe which makes it perfect for making coasters, resin bowls, and serving trays too. It self- levels beautifully and evenly, leaving a gorgeous, glass-like finish. My 4 years old art pieces I made with it are still clear as day! I can sell my art with confidence that it will look beautiful and last for a very long time. I have used it for making completely custom and unique art pieces, as a top coat for paintings, for resin lamps and nightlights, for fabricating things from silicone molds, for custom boxes, trays, candle-holders, etc. This is definitely my favorite resin and one that I can recommend with full confidence!
