This is a Takigen key. Key NO: 【F8503】 12 in stock. These are used keys, so there may be individual differences in how easily they open. However, I am a novice and do not know the points to check. I will ship the keys that look as clean as possible, but please purchase only if you agree to no claims and no returns. The listed price is for one key. Shipping will be by mail. Please note that we do not ship to Okinawa.
