Nice bold ink!
Color: Multi Color-440ml, Size: Multi Color-440ml, Color: Multi Color-440ml, Size: Multi Color-440ml
I was skeptical at first because it was my first time making anything using sublimation. I didn’t know that the ink wouldn’t look as vibrant when it was on paper but I trusted the process. The color was amazing on the coasters that I made. The print quality was great. The ink was easy to install. I’m definitely making this my go to ink!
