This is a prize from the 2003 Pepsi "Get it Online! Silver SNOOPY Bottle Cap" campaign. I believe the complete set of 4 types is rare. I worked hard to obtain these myself, and they have been stored in a box in a dark place. Size: Approximately 5cm tall (including the cap) Made of silver-plated alloy, they have a substantial weight. Due to the characteristics of silver (zinc alloy), some discoloration can be seen. It seems that wiping with a cloth will clean them. Due to aging, there is some dirt on the case and some stickiness on the base. Please check the condition in the photos. Although these items are unused, please understand that they are vintage and have been stored at home for a long time. I will respond promptly to any questions.
