Laptop packaging (Hartington Road BN2)

I bought a refurb laptop online and it came in this. Excellent padded packaging. It's an inflated, ribbed, clear poly envelope. Like a mini double lilo. Internal measurement approx 350mm square. Perfect for sending anything flat fully protected, eg a laptop! It's basically bubble wrap,but much better and in a specific form. Walls are about 20mm thick. Could be used to send books or anything flat that needs protection.
