The perfect gift for all ages!

This adorable tail was originally designed based off of the mysterious black cat, but whatever you see in it is up to you! The simple black color makes it match everything, and it's fun for wearing to all sorts of fun occasions, especially Halloween or creepy themed ones!

The tail was made with a tightly braided yarn core, giving it both stiffness and flexibility, which in turn also gives it a far more natural flow when just walking, or when shakin' that tail all around town. At the base of the tail is a plastic clip, allowing you the ability attach it to a purse to give it some added flair, or a belt loop so you can wear it wherever you want!

:::IMPORTANT NONSENSE:::
The tail is made with a premium brand of 30% silk and 70% bamboo yarn, and feels particularly soft and comforting against the skin; it's light weight makes it comfortable for year-round wear! Not including the keychain ring, the tail is approx. 10 in. {26.5cm} long and depending on if it's smoothed out or ruffled/fluffed a bit, varies between about 1.5 in. wide and 3 in. {3.8 - 7.6cm} wide depending on how fluffed it is c:

This tail is sturdy enough to withstand a good shake, but not for rough tugging/pulling. As a semi-sturdy accessory, it's not meant for rough play/use. Good for children who are careful with their toys, or will only wear/use mildly.

This tail was made with the intention of being a human accessory; it is not a pet toy.

This tail is NOT washer/dryer safe, so be sure to hand wash it in the case of any accidents! Also, avoid ironing/straight ironing too, or at least be very careful and 100% sure you know what you're doing! Acrylic is essentially a form of plastic, and doing this could melt your purchase D:
