Review: Great! - The molds were perfect I just need to make sure to mix the resin appropriately so it cures all the way or it will sag
Review: It works. But I do have concerns - First off, I am no resin expert with molds. I use a lot of resin at work; I own a cabinet shop and we use it with wooden projects a lot. But I rarely use molds I was able to use the molds and put together a paper holder on my first try. It fit together with and stayed together just fine. I like purple abd orange as you can see from the photos. I used mica powder. The problem I had was with the molds laying perfect flat. They would bubble up in the middle a bit. Since not much resin is poured into them, the weight of the resin doesn't push the molds down. I think I could do better on my 2nd try though after using them. But the perfect fix would be to have the silicone molds be thicker. They wouldn't be so unstable. I'm happy with the molds though. I was just doing it as a fun project.

### ⭐⭐⭐⭐⭐ Great!
*by I***! on August 13, 2025*

The molds were perfect I just need to make sure to mix the resin appropriately so it cures all the way or it will sag

### ⭐⭐⭐⭐ It works. But I do have concerns
*by S***N on July 11, 2024*

First off, I am no resin expert with molds. I use a lot of resin at work; I own a cabinet shop and we use it with wooden projects a lot. But I rarely use molds I was able to use the molds and put together a paper holder on my first try. It fit together with and stayed together just fine.

### ⭐⭐⭐⭐ This mold is good made of thick silicone.
*by R***W on June 27, 2024*

This silicone letter tray mold is good, the silicone the mold is made of is a good thickness. The resin is easy to demold once cured. The mold only makes one tray at a time, so making a full sized usable letter tray will take a while (with curing time). I am on my first tray, and I am concerned that I won’t be able to match the color of the second tray to the color of the first tray. The mold is good quality and I think that this is a great idea and a great product, I would recommend!
