HOW ARE THESE MADE?
The caps each have a light in them with a paper tab to remove when it is time to use one. The top has a little light in it that if you press a button on the side, the light goes on. The pen itself is white like a marker type.
HOW DO THESE WORK?
The pens write clear- almost a tiny tinge of green like glow in the dark paint tends to be. It allows you to see a little of what you are writing. When you turn the cap on- the writing lights up and it is very easy to read.
DO THESE WORK UNDER BLACKLIGHT?
Yes, if you were to decorate something that you plan to have in a blacklight room (halloween, lessons, parties, etc), the writing will show up when the blacklights come on. It would be great for a mystery theater too.
HOW POPULAR WERE THESE?
The kids LOVE these. It keeps them busy for a little while anyway. They also made a nice prize for games.
THE BOTTOM LINE
A great item to have on hand for a variety of reasons- from kids and parties, to mystery theaters, these markers are delightful. I love the colors they come in too- the writing is all the same, just the outside is different.
