Lazy Monk Envelope Backpack Jul 31, 2011 Categories: MASH Frames 0 Comment Sometimes it is nice to break objects down to their simplest forms. That is what Ryuta and Aya have done here with an Envelope pack. Their design offers the basic daily needs as a Backpack. Lean, but expansive. Classic bag maker materials, built with incredibly tight craft, and off colors. We are happy to have a limited supply available in our physical, and digital spaces. Check in!
