Thank you for viewing. This item was purchased new, connected to the app, and its operation was confirmed before being stored. All accessories are included. I love ambie so much that I bought too many, including spares. However, my first pair is working fine, and I have too many, so I'm selling these. I will include a pair of new beige socks. They are new, but do not have a box. The yellow silicone cover is a USED item. The paper backing for the double-sided tape on the top lid has been removed. Consider the silicone cover as an extra. No separate sales. I re-confirmed the operation before listing, and it works without any problems. I will clean the item before shipping. It's almost unused and in like-new condition, but it's a home-stored item, so I don't recommend it to those who are concerned about minor details. I will not be offering a discount on this item. Shipping will be via Takkyubin Compact. Cancellations and returns after purchase are not accepted to prevent product substitution.
