How come I can't use a heat tool for popping bubbles?

I think they are just afraid it will melt the mold. I still use a heat gun and haven't had any issues.

Is a release agent needed prior to use?

I didn`t need anything to take them out of the molds. I'm guessing using a release agent will make them easier to release.

Can anyone tell me if there is any deformation after receiving the molds?

No, they are well packed in the box without any deformation and the surface of the mold is smooth.

How do you remove air bubbles in the resin if you can’t use a heat gun or torch?

Use 91% alcohol. It pops bubbles. Also you’ll have less bubble if you set your resin In warm water for about 10/15mins before mixing it. I either sit my bottles in a sink of warm water or I set my poured cups in a bowl of war water. DO NOT HET WATER IN YOUR RESIN. Hope this helps.

Good quality and value for the price.

I bought them to use with cement, not resin. Just made my first batch and they worked very well. I think for resin they will last a long time because resin is not abrasive like cement. Not sure how long they will last with cement, but in the seller's defense they do advertise them for cement. My pieces came out of the molds very easily and the surface is very smooth as you would expect with a silicone mold.

Perfect for Beginners and Fun to Use!

I’m new to working with resin, but I absolutely loved making my own coaster sets with these LET'S RESIN silicone moulds! They’re super easy to work with, and the resin releases smoothly once cured. I really like that the set includes three different coaster designs—it makes it fun to mix things up and create unique sets. Great quality moulds and a perfect choice for beginners or anyone who enjoys resin crafting!
