Thank you for viewing. [Odorless] No smokers or pets in the household. This is a heart-shaped keychain. It opens when you pull the body apart and twist it. (Please refer to photos 4-7) The design is simple, with no printing on either the front or back. I hope someone who can make use of it will consider purchasing it. It has been stored at home, but it is in a clean condition with no scratches or stains. I have taken photos in colors that are as close to the actual product as possible, but there may be slight differences depending on your device. Please understand. I will package it with waterproof measures when shipping. I hope those who understand will consider purchasing it. Thank you for your consideration. This item is available for immediate purchase. Please consider it with the understanding that it is a used item.
