I'm mega excited

I have the envelope because I ordered the green just found mega great. Delivery mega fast, been there the very next day, top. because I had to have gahabt unfortunately times when ordering one of my moments, I have read that it is lit at night. I mega amazed when I discovered that when I turned off the light at night. as in the photo do not naturally lit, I hope that's clear to everyone who has a little clue about chemistry. but still mega! and the green lights and mega intensively with light. I would not hesitate to order again
