We're all about the New York-based line 1PerDiem, that values craftsmanship and functionality as much as it does luxe materials and unexpected details, and we're sure you will be, too (if you're not already). Their lovely site turns one this week (Happy Birthday!), and to celebrate, stock up with this Refinery29 exclusive 20% off promotion! The handbags and jewelry pull inspiration from the gritty yet beloved city that the family-owned factory calls home. We can definitely see ourselves sporting the leather and hardware-embellished goods in all five boroughs and beyond. Just excuse us if we're a bit biased with our favorite piece—the Bowery bag in goatskin and lizard (pictured above). Our office is conveniently nestled on its namesake street, holla!
