Our 16 cavity, reusable silicone one-inch square size mold is just what you need to make a batch of pendants or cabochons in a couple of days!  This reusable silicone mold contains sixteen square wells.  Each well is 1 inch in diameter by 1/4 inches deep.  

These molds are made from highly polished plastic, so it will impart that same shine to your castings.  No post demolding polishing needed! 

Mold color may vary from the picture shown.

How do you use this mold to make square-shaped resin pendants and other resin charms?

1.  Mix and pour casting resin into the mold cavities.

2.  After the resin dries, demold the resin charms by peeling the mold away from the charms.

3.  Finish the charms by drilling a hole for a jump ring or add a glue-on bail.


For optimum mold life, we recommend using the Ultra 4 Parafilm paintable mold release to make sure your castings come out perfectly.

Love the mold hate the cost

I love everything about the mold how thick it is how easy the squares pop out how easy it is to clean. The one thing that I can’t justify though is the cost. I would love to get the other molds, but I just cannot justify the cost.

It’s a little more work but the quality of the product is the same when using plastic candy sheets. I can go to the local store and buy the hard plastic all one shape for three bucks they come out beautifully yes I may have to do a little more work and prepping and sometimes my little hexagons are tough to get out but I can throw them in the freezer and they’ll pop right out.

Is It worth it for me to spend $50 on one tray when I can go and get three trays for nine dollars and get the project done in one shot? No, no matter how exquisite that tray is I will not be buying it again

Fantastic Mold

I have used many silicone molds but this one from Resin Obsession is the best. It is much sturdier than others. My resin comes out clean and easily. Plus the square is the perfect 1 inch size. Thank you Resin Obsession!

Great Mold

This is a really well made, high quality mold and it works great for making little tiles to put together into one mosaic like piece. Easy to use and doesn't use a ton of resin!
