X-Haibei Super Rock Stars Silicone Mold - 2.8inch Diameter Multi-Use Soap, Crayon, Chocolate & Resin Maker - Dishwasher Safe, (Color Randomly Sent)"

So far so good. We have used it 6 times and the crayons have come out great. I will update later if the mold breaks or something.

I made a set of First Crayons for my 1 year old and she is actually able to pick them up and use them. The silicone mold was an absolute pain to clean the crayon wax off afterwards so if anyone knows the trick to that let me know....but it was totally worth it. They're a good size being sturdy enough to not break but small enough for her chubby little hand to hold. (Side Tip if you're also using this to make first crayons: I recommend choosing the darker shades of each color. Babies aren't able to press down very hard so my daughter can't hardly see the pink, yellow, or orange when she scribbles. I wish I had chosen magentas, dark golds, and deep oranges instead of bright ones.)

I used this to melt down all the crayon chunks that my kindergarteners have finished with to make big, multicolor crayons for them. After peeling and making sure the crayons were broken up enough, I added them until the molds were a little more than half full and cooked them for 17 minutes at 250. The first time I didn't wait for them to cool enough, so they cracked, but it was actually very easy to remove them from this mold when cooled, because the mold could be pulled off around them.I would definitely recommend this as a mold for crayons, soaps, or other similar things!

I got this to make new crayons out of old crayons. We put pieces of old, broken crayons in the shapes and heated them in an oven until the crayons melted. The new star-shaped crayons popped out easily. The mold did well in the oven and cleaned up easily. The new crayons came out with clear, detailed designs from the mold. All that I could have wanted.

Made chalk with these molds with my daughter. So fun. Great detail, smooth edges, deep pockets. Very happy. Have used many times.

Used these to make rainbow crayons from all the classroom crayon 'bits' left at the end of the school year. Made a nice little craft gift for each of my students on our last day of school. Worked really well, but I will say there was an odor from them in the oven. No, it wasn't the melting crayon -- it was definitely these molds. Would still recommend!

Used this mold to repurpose some broken crayons and it worked great! Held up in the oven great for the time needed. I'd definitely recommend these to anyone looking for something nonstick.

Perfect for the crayons I made. 4 full crayons to fill about half each cavity. It is a bit hard to clean now and I would only be able to use it for crayons but it's fine.
