Light sensitive PU makes your T-shirt more special on UV & Sunlight.
It looks just white color PU in doors, but as soon as it is exposed on UV & Sunlight, the unique vinyl will display its "true" colors.

Heat sensitive PU makes your T-shirt more special on temperature change.
It turns to white color when touched with warm hands and returns to original color when cooled down.

Experience the unique feature of color change and make youself special

Happy New Year :)
