@@GokuNKrillin yes it will be fine, just don't be the people that have the uv lightstrips and leave them on all the time, the box will fade some no matter what, but it won't be that noticeable.
I bought a small cheap blacklight it’s bright but it doesn’t give the glow in the dark the full effect and it glows for 10 seconds after shining on it for 5 mins straight
So i have a question you said that a regular flashlight won't give you the best results my question is how do you make a regular flashlight GIVE you results
It is not entirely proven because no one has risked leaving it there for a long time, however, it is very likely that it will become discolored if you leave it directly in the sun for a long time. But if you only leave them in less than a minute, it shouldn't be a problem as long as you don't do it too often.
