Supervised by Aichi Prefectural Police, this is a pass case-style security alarm with a removable strap. I purchased this previously, but it has been stored unused in its box. Please note that I took it out of the box once to check the operation and take photos. It can hold small change, transportation IC cards, and credit cards. (See photo 10) - Brand: Paskel - Color: Black - Design: With security features - Strap: Removable Width: 10cm, Height: 8.5cm Please feel free to ask if you have any questions. ^_^
