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.
