Easy demolding
I use this for my left over resin from bigger pen blank pours. Nothing wasted. Easy to demold. Will use the spheres in some larger projects later. Getting the thicker resin in some of the smaller spheres required some scraping. I should have used a toothpick to hold the tiny sphere mold opening wider. Overall very pleased with this purchase. Mold seems high quality and should be durable - nice thick walls and sides hold the spheres away from the surface so they stay round.

Excellent molds for resin projects!
These molds are high-quality and well-made — the silicone is thick and durable, yet flexible enough for easy removal without damaging the pieces. The variety of sphere sizes is perfect for different projects, and they hold their shape beautifully. I’ve used them multiple times, and they’ve stayed in great condition. Perfect for resin artists of any skill level!

Smooth Finish Easily Demolds
I am bouncing with Soap Ball laughter! I purchased this mold for my soap projects. This mold is 100% what I hoped for. The various sizes of the balls are exactly what I envisioned. Perfect spheres in assorted sizes. The rubber is smooth and demolds easily .

I purchased these sphere molds for resin crafting, and I'm very impressed with the quality. The molds are sturdy and well-made, and the spheres they produce are smoot. I've used them to create resin balls for jewelry and decorative pieces, and the results have been fantastic. The molds are also easy to clean and maintain.
