White letterbox boxes E-flute - 350 x 230 x 28mm

White letterbox box 350 x 230 x 28 mm – elongated with extra length

This elongated white model offers over 5 cm of extra length compared with an A4 sheet, handy for documents with a protective layer or an insert. Since 2007, we have been the go-to wholesaler for letterbox boxes. Thanks to its flat design, the shipment fits through the letterbox, so the recipient does not need to be at home. Mind the internal size: 350 x 230 x 28 mm (length x width x height).

The sleek, flat shape delivers a neat shipment to the recipient's letterbox, while you benefit from the low weight of E-flute board. For bulkier orders, our folding boxes offer a suitable alternative.

Documents with an insert: an A4 sheet with extra protective board or a leaflet.
