Hamburg-based online retailer Frontline is opening a pop-up store in its hometown on Sept. 5. The 240-sq.meter store will offer close to 500 products from brands such as Carhartt, Cleptomanix, Iriedaily, Casio, Burton, Nike and Pepe Jeans. The store, however, will function like a showroom; products won’t be sold there but visitors can try them on there and order them instantly from Frontlineshop.com. The items will be shipped for free within 24 hours.
