I have a keyholder and a file that I purchased at a dinosaur exhibition about two years ago, which was a collaboration with Peanut (Snoopy). The file is A5 size, and the keyholder is approximately 6 cm in both length and width (excluding protruding parts). The keyholder has been displayed indoors, and the file is unopened. Please refrain from purchasing if you are looking for a perfect item, as it has been stored by a private individual. Please let me know if you would like any additional photos, etc.
