Prices include delivery and can change, so check the price on eBay before you buy. How it works.
Every price includes delivery. The green row is the lowest price per box for that type. Click a total to see the listing on eBay.
A 4×4×1 inch (100×100×20mm) box holds about 0.2 litres. Most sellers list the inside size, so the item you're packing needs to be a little smaller than this on every side to leave room for padding.
Single wall board suits light and medium items. Die-cut postal boxes arrive flat and fold into one piece, which makes them quick to pack.
Pack size matters. For single wall postal / die-cut boxes, buying 200 instead of one takes the price from £1.06 to 6.3p per box, which is 94% less.
