This is a complete set of all 4 bottle caps from the Powerpuff Girls Collection Egg 2, which was sold in gashapon machines in 2001. They have been stored at home for over 20 years, unopened. I took the photos while they are still sealed, so they may be a little difficult to see. One mini-book is included. Please understand that these are items stored at a private residence and are used, even though they are unopened. Please refrain from purchasing if you are concerned about minor details. I will respond to any questions promptly.
