18 Color Epoxy UV Resin Pigment - Liquid Epoxy Resin Dye Transparent Colorant for UV Resin Coloring, DIY Resin Art Jewelry Making - Concentrated UV Resin Colorant for Paint, Crafts - 0.35 oz/10ml Eac

For the price and array of colors in comparison to the price of trying to buy these solo-bottled at a regular art store? This can't be beat! Highly recommend trying this colorant out. A few other resin artists have asked what I use and said they would be purchasing. With 18 different / varying colors, it's really easy to mix your own custom colors as well. I also haven't had any issues at all with leaking / overdripping -- besides using the "Cream" white color, but I squeezed that one too hard. Oops! The only, tiny little thing I have an issue with was this statement on the product page here: "A LITTLE GOES A LONG WAY - High concentration of UV resin color pigment, just a drop and you will be shocked by the strong dyeing effect." Honestly, it takes a lot more than just 3 drops (as it states on the individual bottles) to make a nice, deep, vivid color (I counted about 8 - 13 drops depending on the color to get a rich, heavy coloration), but with how well it works? That's small potatoes to worry over. 5-Stars overall for everything. When I run out (which hopefully won't be any time soon), I'll be purchasing these again so long as they're available!

Work great and easy to use

Awesome, colours are great and very strong, needing only a small amount to add colour to resin.

These are extremely pretty, just don't use too much foe UV resin, we found that they didn't cure properly when we used a lot of color concentrated in one area.

Disclosure: I bought this product at full price like a normal person. 3D printer UV resin is expensive enough already, and paying a ton of money for colors I might use a few times feels wasteful. I could say a lot about this product, but all you really need to know is 1) it's well packaged, 2) it's easy to mix thoroughly, and 3) it totally works. The pink in the pictures is from the "peach" color, which was very obviously a deep pink looking at the bottle. All the colors are named after fruits or flowers, so it'll be nice and easy to keep track of what I used in my notebook. I put 10 drops into 30mL of white resin (the mixing cup picture is after 5 drops), and the results speak for themselves. A drop is officially measured as 0.05mL, so there'll be about 200 drops in a bottle. Given all the different colors included, this set will make a LOT of pretty prints. I'm neeeeever buying pre-colored resin!! PS: I also bought amber-tinted glass bottles to store my mixed colors in (https://amzn.to/2NZE6gU)
