Resin Molds for Coasters,6 Pack Silicone Molds Kit for Casting Epoxy Resin UV Resin,Include Round, Hexagon and Square,with Resin Mixing and Measuring Tools

I was using a thick resin for my first use odd these and the results are mixed. The molds with a raised top edge (bottom of mold) formed p bubbles under the decorations I place, so I couldn't really see them. This left voids around the edge. Kinda cool look, had I been aware so I could duplicate, but I wasn't aware. Three flat, even molds resulted in perfect pieces.What I learned:1. To get an even bubble free pour, use a much thinner resin, mix it slowly, let sit a few to allow billable to surface, then pour slowly. 2. Use a needle tool or a small ball tip tool to make certain resin is filling properly and to pop or remove bubbles. Add decorative materials slowly.3. Seal paper, wood, & other porous items before embedding in the resin to prevent discoloration and/or adding bubbles.4. Use a good mold release appropriate for your resin. I used a spray and applied 3 very light coats, allowing each to dry.

I'll be using these to make resin coasters. I especially appreciate the zip bags the molds came in. So much better than the usual glued bag that I have to cut. I doubt that I'll use the finger cots that were included, but I will most definitely be using the little stir sticks for placing small objects in the edges of the coasters. I only wish it came with more of those little sticks. Can't wait to use these molds!

After I receive it, it is not good for making full sets at one time to make a set of coasters you will have to buy 4-6 sets. But they are very good quality.

Perfect for resin mold.

Don't be fooled about the sizing

Use shipping tape to clean. Easy to remove products from molds with no additional sprays. Also bag they are shipped in is useful to store them in! :)

Para desmoldar están perfectos, la silicona es gruesa, ya realice la primera linea de posavasos y salieron tal cual, brillantes y bien moldeados.

I love these! Was able to use them for many different keepsakes. Super easy to use and maintain.
