These brown long tuck chipboard boxes were originally designed for the engineering industry to hold things like nuts, bolts, washers and nails – that means they’ve got a lot more strength than you might imagine. Ideal for packaging weightier small parts and components, thanks to an impressive strength derived from the clever design, with a long tuck which gives our chipboard boxes a double front and base, and an extra tuck-in flap at the top. Manufactured in brown lined chipboard and supplied flat in packs of up to 1000 boxes. We have 14 sizes available, ranging from a 38mm x 26mm x 38mm up to 102mm x 76mm x 156mm.
