The Pocket Clip is one of those improvements that we are excited to introduce.  The Pocket Clip is no ordinary clip. It is a unique and versatile accessory that will further ease your pocket carry - and here is the cool thing about it: The Pocket Clip is not only a stand-alone product. It is also a modular AND mobile accessory to all M-Series wallets. Designed with the Dango DNA of sleekness while combining 6061 CNC machined aluminum with formed stainless steel and mil-spec bolts, it is a product that you can truly appreciate! Lets go over the Pocket Clip being a stand-alone product first: The features of the Pocket clip include a handful of functions: Of course, a pocket, belt or strap clip, a cash clip and a bottle opener. With it's generous key hole, It can either be used as a key-chain, or as an anchor to tether your most precious everyday carry! Now here is the Pocket Clip being a companion to your M-series Bifold Wallet: While serving a great clip to tether your Dango Wallets to, the Pocket Clip can be easily be installed onto your M-Series Bifold wallet by simply sliding it through the fold of the bifold pocket. In this configuration, it serves as a great cash clip - and not just for a few bills - it can hold up to 10-12 bills, maybe more.
