These kits were originally sold through a book club and were not available to the general public. Troll began producing these kits in 2001 and they are no longer being made by the manufacturer. Because of this, some of these kits are difficult to find. Others are no longer in existence. The club charged 12.95 +S&H per activity kit.

The original ad sent with one of the packages was "In this spellbinding kit, your child will perform mesmerizing experiments that will take them into the world of Harry Potter. Along with an illustrated, step-by-step activity guide, they"ll receive special (and safe) items to complete each activity. Each activity is fun and educational!"

Every activity kit comes with lab binder pages that describe the experiments that can be done with the included materials. They also explain the reasons why each experiment worked. This is a highly informative booklet for students of all ages! The kits were broken up into two different series. The first is the Spells & Potions series. This series was introduced as a complement to the first book, Harry Potter and the Sorcerer's Stone. Each package (except for the first) contains a lenticular card featuring a picture on one side and activity information on the other. Only the side with the photo is the "moving image" looking side. The second series is the Harry Potter and the Chamber of Secrets: Spells & Potions II series. Each activity begins with a quote from the Harry Potter and the Chamber of Secrets novel. The page numbers (of the paperback) are given for reference. These packages also include a Witch & Wizard-in-training Notes Poster that has a picture on the front and an area on the back for note taking.
