This is a versatile product that can be used on many surfaces, both porous and non-porous. I ordered this 3 pack to use on glass charms but have previously used alcohol inks on metal, clear acrylic, glossy paper, and cardstock. Due to being a dye based color there is not a lot of fading. Also due to the alcohol base the liquid does not wear and thin paper and also dries quickly. Here is a link to the project I used these products on.
The colors are so pretty. Perfect for altering clear plastic buttons or bling.
So happy to see new colors!
