Speedball Fabric Block Printing Ink, Transparent Extender, 2.5-Ounce Tube

Its perfect for what I used it for. I needed it to make a rorschach cosplay moving ink blot mask the base is just used to mix with the thermochromic powder. Works right out of the tube and air dries :) ot does leave a slight yellow film on white fabric but its not noticable.

This ink is fantastic, I got yellow, red, black, and transparent, they all work wonderfully. If you are going to use these things, which I highly recommend, just make sure you don’t roll out more than you need because it does tend to dry/come up quickly, think itself takes about 5-9 days to dry fully, but once it does it is machine washable, I have shirts that I made at Christmas time as gifts that still look almost exactly sharp and clear as they did when I printed them.

This product is amazing. Mixing it with the ink makes the speedball fabric ink so much easier to work with. It makes the ink smoother, less tacky and slower drying.
