This is definitely not your regular wallet, although I am quite concerned how we can get that on airplane.

Featuring high-quality materials, the Dango EDC Wallet Collection features two different wallet types: the D01 Dapper Wallet and the T01 Tactical Wallet. Both wallet use anodized and CNC-machined 6061 aerospace-grade aluminum. It is then hand assembled, paired with rich leather and held together with military spec bolts.
