Price reduced! Cat Silhouette Hairball Keychain Ball Material: Glass (as stated on the site) Ball Size: Approximately 1.5cm in diameter Small size: Please check the images *This is an imported product. You can put your beloved cat's hair through the hole (approx. 3mm) in image 3. It's difficult to insert the hair with a smooth, needle-like stick because the hair will slip, and it's also difficult with a toothpick because the hair will get caught. It's easier to insert the hair if you wrap the tip of a toothpick with masking tape or cellophane tape before using it. Image 5 shows a picture of me making one for my own cat. Please refer to it if you like (˃̵ᴗ˂̵) It will be wrapped in cushioning material and shipped via Yu-Packet Mini. *I also have other cat and dog hairball capsule keychains for sale♪ My cat's hairball gacha Cat hairball container my cat keychain Gacha cat hairball clear container
