ABOUT US
Here we would like to present GRYF photoluminescent materials to you. Our products are entirely the contribution of Polish technical thought, manufactured in Poland and protected by the Polish patent low. Research shows that our photoluminescent products are 3 to 80 times more luminous than the products of world-renowned companies. The time of light emission is 14 hours and the time until the afterglow disappears is 14 days. This places our products at the absolute global forefront. The lifespan of the luminous layer is defined as more than 50 years, and it only refers to the wear of the protective layer.
