I've kept this in a dark place since I received it, without using it. This is a set of two. It's mini-sized and small, so you can attach it to a bag, etc. The cold temperature makes the bag more prone to tearing. There is a possibility of damage during shipping. Replacement bags are not included. Please be aware of this. Due to being a foreign product, there may be minor scratches or dust. Please refrain from purchasing if you are sensitive to such things or are looking for a perfect item, as I am a private seller. I will ship with simple packaging and anonymous delivery. Instant purchase is OK ⭕️ Feel free to comment if you have any questions. Thank you. Cat Neko Nicomark
