This review is from: Slinky Science Fun Lab Secret Codes SLY01100 (Toy)

I purchased this for a friend's daughter and assumed that it came with two invisible marker's and two developer marker's that make the invisible ink show up. You get two of everything else, but only one set of markers (one is an invisible ink marker, the other the developer). I paid $6.99 for mine at Hobby Lobby. It is worth about $2.00. I would recommend ordering the set of four Invisible Ink Ballpoint Pen & Black Light 4 pack from DDDiscs on amazon.com. Yes, they cost about $3.00 per pen ($11.97 total). While the pens are not actually ballpoints, they are a marker style and work great! The blue/purple light on the end is used to make the ink visible. Then for $7.99 on amazon.com order the book "Top Secret: A Handbook of Codes, Ciphers, and Secret Writing."
