I have several items from Koogel that I am happy with and these molds are no exception. They are great quality and very well priced. I’m a novice at working with resin and I found these molds very easy to work with. I’ve seen the reviews that say they tear but I had no problems. With patience and a gentle touch you can roll these down to release the resin with no tearing. The molds are true to size and plenty sturdy. The colors of the flash powders are vibrant and beautiful. Working with resin has opened up a whole new world of crafting for me. The ideas are endless. No matter where I look, I see another idea that I can use these molds for. This is an absolute ideal set that anyone can use and enjoy – from novice to expert. I would definitely recommend this set.
