  • I used this for a quick and easy mold box.
I make miniature silicon molds for resin casting. This has always been a bit irritating, especially for casting smaller objects. I saw this product in an online article and decided to give it a try. It works well; quick setup, littler leakage and well constructed to fit together. The product consists of 4 corner pieces, 8 side pieces and 12 spring clips allowing construction of boxes ranging from 2" by 2" square up to 6" by 6" square (or 8" by 4" rectangle). Maximum height is 2". Also included is a role of 1" double-sided tape to help seal the mold from leaks. I didn't use the tape preferring clay as a leak sealer. It works very well. I made a 2x2 inch mold of a cowboy hat and head. No leakage from under the mold, virtually no flashing where the parts fit together and easy clean-up. I just wish the mold box pieces were taller than 2 inches. ... show more

  • Best on the market
Don’t bother with the other brands to save $3. These are the best in the market. They are hard abs so they keep the form of the mold, they seal perfectly with just one clip. The others are silicone and they are flimsy and don’t seal. If you need to cast epoxy in them just get a silicone spray or mold release to coat the surface. ... show more

  • SFX Flat Molds
I recently purchased this, because I didn't want to have to DIY a mold box and I figured for the price I outta check it out. It did not disappoint! easy to use and remove! I'm going to purchase more so i can run more flat molds at one time!

  • Great Item
I bought this to make molds in and it's great! It's easy to use and very sturdy. Make sure to clean any sticky residue from the previous use of double-sided tape from the bottom between uses. Otherwise, it makes a build-up, even from just two uses, and doesn't allow for a complete seal of the casing. It WILL leak, but that is a user error. ... show more

This seems like it will work I have not used yet.

  • It’s ok but disappointed
Although this is adjustable it still seemed to be a challenge to get the right size to mold an item. I wish the walls were taller. Found out the hard way that you still need to hot glue it to a bottom piece otherwise it will leak your product out the bottom.

  • Works perfect
I have made multiple molds of varying size now, works perfectly. Allows for quick mold box sizing, with little prep work for a pour. I suspect folks complaining about leaking are molding for the first time and would mess up their pours with ANY molding aid. It's an aid folks, not a magic foolproof box. Double clamp the sides, seal the bottom. Just like you would have to do with any other mold box. Cheap, quick, and relatively fool proof. ... show more
