Wonderful finished product. Wish there were more sizes available.
Rated by: Frank B. in Austin , TX
I just started doing resin casting to make pen blanks I turn on the lathe. These little molds work great. They are inexpensive and you can use them over and over. I found that I do not need any release agent when using these. Great product. I'm going to buy more so I can pour more molds at a time.
Rated by: R.E. P. in Dallas, TX
Excellent mold for casting Polyester Resins. No molds release is required. Very sturdy, does not warp, twist, or bulge during or after use.
Rated by: Jeanne W. in Glen Ellen, CA
These molds work very well. It's easy to get the dried resin cast out of the mold. The molds clean up easily for reuse. My only complaint is that I wish they had more larger sizes.
Rated by: Teresa S. in Britton, MI
These work great for my resin weights. In fact I'm going to order more :)

I use this to mold resin and clay jewelry pieces. They also work as molds for large mixed media pieces I add to my sculptures!! For the money, these are amazing!
Rated by: carol s. in champaign, IL
I was lucky to find your website. I could not find molds in any craft store in my area. They work great, and I have used them many times.
Rated by: James S. in Vancouver, WA
I purchased different sizes of molds for PR casting of pen blanks. I was a little put off by the price, but after using the molds, I am very happy with them. I'm guessing they will hold up for quite a while.
Rated by: Debra B. in Heartland, OH
Works well for poly resin casting without the need for any kind of release agent. I just turn mine over and slam it down on my cabinet-maker's workbench and my set poly resin casting pops right out. These are excellent molds for poly resin casting, IMO, FWIW.

I used the resin mold to pour ULEE into. Worked great - just a little larger than I realized.
Rated by: Leo F. in Pascagoula, MS
I'm using these molds to cast polyester resin for pen blanks. They work perfectly. Resin pops right out without any release agent and there's no cleanup necessary.

Great products

Products were great, just as shown.
Rated by: stabby p. in chicago, IL
these molds are great. ive just started to do some resin casting, and i started out trying to molds of my own creating, i.e. steel wood etc., these molds have been a vast improvement, especially in the areas of clarity and cast removal.
Rated by: Jessica G. in Birmingham, AK
The best! If you've been using soap or candle molds instead of these made specifically for resin you are in for a treat. Perfect, easy release every time - just tap the bottom against a surface and piece pops right out after only about a day of setting time. Highly recommended!!
Rated by: Richard D. in Jacksonville, FL
Product worked perfectly. Molds are very sturdy and the resins slide right out once they have cured and hardened. I am certain to be buying more of these in the future.
Rated by: Paula B. in Hackettstown, NJ
Perfect - just what I was looking for, icluding the shapes and sizes. Easy to use and easy to RELEASE. Cleanup a breeze.
Rated by: Daniel Y. in Reno, NV
fine little molds. Heavy but bendable material. think tupperware. I really treat them rough when removing the set up resin and they have no problem handeling it. The choice of sizes really suited my various needs as well.
Rated by: Jim M. in Kaukauna, WI
These molds are great for what I need them for (making pen blanks). I use them with polyester resin, and after a day of setting up, I can slam them on the counter top, and the PR just pops out. What more can you ask for??
Rated by: John S. in Miami, FL
Great for small items and easy release.
