These reusable 2 oz cups are great for making lots of Little Windows. You can double or triple your batch size for larger pieces like ornaments. Be sure to stick with the 2:1 Part A-to-Part B mix ratio and follow all instructions to ensure proper results. Wipe clean with dry paper towel if resin is still liquid, or allow to cure then roll the cup in your palms and push the bottom to remove set resin. Remove any cured drips with your fingernail.
