Let me start by saying, these epoxy resin pigments are a game-changer for anyone into resin art. The 27-bottle set offers an incredible range of colors that can transform any resin project into a masterpiece. I've used them for everything from jewelry making to coating my bike parts, and the results are consistently impressive.

The high concentration means you only need a few drops to achieve brilliant colors. I was skeptical at first, but after testing, I can confirm that a little goes a long way. The colors stay vibrant and don't fade over time, which is crucial for lasting art pieces.

One thing to note - some bottles arrived dried out (especially the fluorescent yellow). While this was disappointing, the majority of colors worked perfectly. Just make sure to shake them well before use!

What I love most is how easily these mix with resin compared to mica powders. No clumps or uneven distribution - just smooth, consistent color every time. You can create anything from translucent effects to opaque finishes by adjusting the amount you use.

The squeeze bottles make application precise and mess-free. I've successfully used them not just with epoxy resin but also mixed small amounts into clear coat for automotive applications with stunning results.

While the product isn't perfect (some quality control issues with dried pigments), the vibrant colors and ease of use make this set worth it for serious crafters and beginners alike.
