is glow in the dark t shirt uses the best paint inks to stay in color and shapes、 with the high standard screen printing techniques that accumulated for 20 years. this product is shipped to you straight from the factory、 that gives you the best deal of premium t shirt in terms of bright prints、 soft material and best after-sale services.<br />Please note that this T shirt CANNOT glow in dark straight from package. You need to expose this t shirt to daylight/ normal light to absorb light for 5~10 mins before it shines in dark. And the longer it is exposed to strong light、 the brighter it shows in dark.<br />Hope you have a pleasant experience purchasing my products、 and I wish to hear any feedback for further product improvements. Thanks!
