Epoxy Resin Pigment - 15 Colour Liquid Epoxy Resin Dye - Highly Concentrated Epoxy Resin Colourant for Resin Colour Art, DIY Crafts Making Supplies - AB Resin Colouring for Paint, Crafts - 10ml Each

There is so may different colours to use from and the bottles tell you how many drops to put for how dark you want you colour to be. It gave such pretty colour for my resin. 10/10 WOULD BUY AGAIN!

I bought this one to colour epoxy resin compound. I works like a treat. The more you add the more intense the colour. Important to note that some colours are more transparent than others, blue and ping for example has a fantastic transparency. White and black however are quite opaque, perhaps intentional as one usually would like to have a solid white or black.I am not sure if it is me but it feels like the dye ever so slightly thins the epoxy compound (talking about 10-20 drops into 40ml compound). This does not impact the end result however causes bubbles to disappear very quickly, so an unexpected benefit.Recommended.

Arrived well packed. Before first use the nozzles of the bottles needed to be pierced with the needle tools provided (pretty straightforward). This kept them safely sealed in transit. The colours need to be well shaken before use but mix well into the resin and are concentrated enough to give a strong colour without too many drops. I add them one drop at a time until I get the strength I want. They are nice and clear colours. My only quibble is that there are more shades of red than anything else.

It was a gift for me and I wanted to play with my grandkids so will help me have fun.

This product is very good the pigment are beautiful

Oh, such a mixed bag. I like the colours. Some of them, especially the blues, have a lot of staying power, even in sunlight. The weaker colours -- I'm looking at you, yellow -- not so much. My main issue though is the design of the bottles. The box comes with little pins to help pierce the applicator tips, which are useful, and the pins are brightly coloured, making them hard to lose despite being so small. My issue is that, once pierced, the box is designed so the bottles lie flat, and the caps don't fit especially well, meaning there can be a lot of leakage. I didn't pay for something just to stain the box it came in, so it's quite wasteful. It's also hard to find a container that I can put the open bottles is, as they're annoyingly small.

Great item, Fantastic Quality, Amazing Results

Be careful not to use too much! I made the mistake of putting too much colour in the resin, initially. Turned out well as it happens, but very different to my intended outcome. The colours are strong and rich, but use sparingly, depending on the desired outcome, you may need to test how much you need first before commiting to your final project
