Vibrant results

These mouse pads give vibrant results for your sublimation, I would recommend that you take a lighter and gently go around the edges to keep them from fraying over time

Almost great
Number of Items: 11
All pads are individually package with resealable plastic pouches which is nice when reselling. Sturdy backer material and it does not slide easily. These mousepads have a subtle gray or even bluish-gray tint that will slightly distort the color of any image pressed directly on them. The result is that no design containing white will look quite right and other colors may look a little faded or a bit off-color. Overall good buy, but these have some limitations when using sublimation ink and not HTV products. Will likely buy again as end result was a happy customer after some design elements were modified.
