Thank you for viewing! I want to be with my pet all the time! This is a keychain-shaped transparent case that fulfills that dream, designed to hold your pet's shed hair. For loving owners who can't bear to throw away the shed hair (hairballs) after brushing... this keychain is highly recommended! 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. I opened it for the photos, but it is a new, unused item. You will receive the item shown in the first photo. (The second photo is an image.) Please understand that this is a Chinese product stored by a private individual, and purchase accordingly.
