Gift from back home(Korea)…I have not been home in 39 years so I’m not familiar with this product. 3 in 1 convertible bag. 11-13" LAP-TOP STORAGE FULLY DETACHABLE. FULLY REVERSIBLE CROSS & TOTE & SHOULDER PIGMENT COATED FABRICS ED BAG DUPLEX IS A PRACTICAL BAG, REINTERPRETED FROM ED BAG ORIGINAL, WITH A FOCUS ON STYLE AND ACTIVENESS. ITS BIGGEST APPEAL IS THAT IT ALLOWS FLEXIBLE STYLING ACCORDING TO CIRCUMSTANCES - THE BAG COULD BE TRANSFORMED TO A SHOULDER BAG, A TOTE, OR A CROSS-BAG DEPENDING ON THE SITUATION. MOREOVER, INSIDE THE CROSS-BAG, AN 11-13 INCH DEEP POCKET IS ATTACHED FOR STORING A LAPTOP, WITH CUSHION FOR BUFFERING, WHICH MEANS YOU DON'T NEED TO CARRY AN EXTRA POUCH. Cotton/nylon blend with pigment coating.
