What do you mean by black light? If I use them on paper, will they glow in the dark?

They are bright in normal light, but if you have a black light, they glow very brightly.

A black light is a special kind of light that makes whites and bright colors glow. They won't glow in the dark with no light or an ordinary light bulb.

they are only neon color sharpies I haven't used them they were for my granddaughter but they don't glow just in the dark but if you use them and shine a black light on them they show up with a glow

No, they don't light up, and so the answer is, you don't know what you're pressing when it's dark. So I don't recommend using it in the dark. :-)

Sorry, I have not tried these on a black board. However, the crayons are not that bright. You may want to buy some neon colored ones for the black board.

Sure I use them for forms for my business and pen copies well. It will all show up black though.

Yes, black light. They look awesome. Probably the same if the photo is the same. They come robber banded together with no other packaging. Amazing fun at parties.

They don't show up on black poster board. You get the same look that you would if you wrote on black posterboard with a hilighter. If you write with them on black, it will show up under a black light. Someone said that the blue isn't UV reactive, but this is not true - it DOES glow under a black light, it's just that blue is more difficult to see than the other colors. I own these markers and can assure you that all the colors are UV reactive.If you want to write on black posterboard, you will need to use a paint pen/marker.

Yes! The lighter colors show up really well on any dark papers. They work nicely on matte and glossy finishes.

I have glow in the dark pebbles. Black lights never seemed to do much to them. I think the Light has a hard time penetrating through the water. But that's just a guess. Go buy yourself a black light poster. Then if the pebbles don't work out you've got yourself something sweet

No they do not light up. A light can be added though, but make sure it's not too bright because the material is just a heavy paper not like a lampshade.

The best answer is no, because they are too fine of a point to show up well on black. Your best bet would be pastel pens with a bolder point.

Yes. Definitely some of them glow. I received them in the evening. I put them in one of my bedroom draw without turning on the light and there I noticed some glow though not sure which colors.

Only the fluorescent colors will glow under a black light, there are 5 of the fluorescent colors in this set. No, they will not write on plastic.

Yes, they really do glow in the dark. They are pretty pastel colors in the light!

Yes, anything flourescent or bight white will glow, it works just like a regular blacklight.

These are markers, you cannot see anything on the paper (maybe slightly damp, but it dries) until you shine the blacklight on it.
