Can I just say that the company itself is amazing? I purchased a gallon of resin, and when it arrived, Part B was spilled all inside the box. I contacted the company and they replaced the entire order, not just the Part B.
Recently I have been trying other resins. As crafters know, the cost of resin is climbing, so I have been looking for more reasonable prices with other resin brands. Trust me...don't bother. Istoyo is it. It's the best. Don't waste your money on other brands. This one has a reasonable cost (especially if you wait for sales), is crystal clear and very few, if any bubbles. I have learned my lesson. I'm not going anywhere else from now on!
