Review: Makes about 20oz of silicone, AMAZING PRODUCT - I LOVE this product! I've used it multiple times. Dries within 30 minutes, has about 5 minutes of working time. Will need 2 Kits for larger pieces. It makes about 20-25oz of silicone. CAN be layered, I had a huge piece to mold and didn't have enough to cover the top so waited about a month to finish the process and it still came out perfectly. I mix mica pigment into part A to make custom colors as well, always cured perfectly. Very durable mold. Great for resin crafts. Only problem I have is that it may have too many bubbles for someone's liking. The mold is always perfect but can look a little bubbly.
Review: Definitely recommend! - This mold material is amazing! I've been using alumilite silicone mold to make my molds and it works well but hasn't seemed to hold up as well to multiple uses. I decided to try this material instead. SUPER easy to make the molds and the set up time is so fast! In less than an hour you've got usable molds. I've only had a few areas in molds that didn't set up completely but I believe it was due to debris being on the container for the mold and it hasn't affected how well the mold works. I do find that the set up time of the easy cast resin is a little bit longer when using these molds but the de molding process is much easier and cleaner with these molds than the previous ones. I've already used my full first batch and made about 25-30+ smaller molds for numerous casting purposes. Definitely recommend this product for both beginners and experienced mold makers. The material being some cloudy clear is a big help too because you can see how filled in your casting is or where the colors are going if you use pigments like I do

### ⭐⭐⭐⭐⭐ Awesome stuff
*by S***Y on July 3, 2021*

I really like this, I’m new to sculpting , and I’m learning how to use monster clay. I want to sell my art , so I make a mold of it and then cast it with Sculptamold. This works great ! Very easy, and it cured/hardens quick like the box says 30 minutes , it’s super sticky though I wasn’t wearing gloves so it got all over my hands , but I just let it dried and then peeled it off. I Ofcourse wish it came in a bigger size that wouldn’t break the bank for me ! The mold comes out bendable rubber which is fun because I’m sure it should last , and I just need to make a 1 side mold because I’m gluing the smooth side to a canvas .
