Vibrant, Rich Colors
This is my absolute FAVORITE sublimation ink. For the price, it's the best you'll find the canisters are easy to use, don't leak, and lasting for months.
The bottles fit perfectly onto the eco tank. The colors are vibrant, rich, transferring to piece exactly as it should. These work like a dream and I'm a loyal customer, for sure.
