I just started my business with Resin art and crafts. After so much research, I came across this website that offered a lot of things I needed. The shipping is super fast which all of the things I ordered came in time for my launching. The coasters are so easy to use. I will always use Resin Obsession for my products needs in the future. ❤️

Oh gosh Quinyona, thank you so much!

These are beautiful Charlene. Thanks for sharing!

Geode mold

I just finished my 1st pour using this mold. I can't wait to demold it tomorrow! The attached picture was taken about 30 minutes after I finished pouring. Love it already.

Very good quality

This was my first geode style mold so I was not sure what to expect. Turns out the mold is quite thick and sturdy. I did a pour and removal was easy. I like the depth as well.
