Thank you for viewing! I want to be with my pet all the time! This is a transparent keychain-shaped case that fulfills that dream by holding your pet's "shed hair." It's a keychain recommended for loving owners who can't bear to throw away the shed hair (hairballs) after brushing. I took a picture with a 5cm white USB memory stick to show the size. The actual product you will receive includes only the keychain and its accessories; the USB memory stick and the acorns are not included. Please understand that this is a Chinese product stored by an amateur. *If you wish to purchase multiple items, please inquire in the comment section.*
