Siser® Glow in the Dark Heat Transfer Vinyl – 12" / 15" / 20"

Siser® EasyWeed® Glow in the Dark is a white polyurethane heat transfer vinyl that reads as a clean off-white in daylight and glows once the lights go out. Charge it under any light source for a few minutes and it holds a visible glow — brightest at first, fading gradually over the following hour or two.

It cuts and weeds like standard EasyWeed, so there is no new technique to learn. Available in 12", 15", and 20" widths.

Features

• Charges under light, glows in the dark — no batteries, no coating, it's in the film.
• Cuts and weeds like EasyWeed — same handling as the film you already run.
• White in daylight — the design works in both states, not just at night.
• Presses on leather as well as cotton, polyester, and blends.
• Three widths — 12", 15", and 20".

Recommended Fabrics

• 100% Cotton
