Which single wall box size do I need?

Single wall or double wall?
Single wall boxes are one layer of B flute corrugated board, and most sizes are rated for 5 to 10 kg. That covers clothing, gifts and light homeware. Books and tools get heavy long before the box is full, so for dense contents or anything over 10 kg choose a double wall box. The 12 x 9 x 9, 12 x 9 x 12 and 18 x 12 x 12 in sizes come in double wall too.
Buying single wall boxes in bulk
Every size is a FEFCO 0201 standard flap box, supplied flat. The minimum order is 10 boxes, and each size has price breaks up to wholesale quantities, applied automatically in the basket. Prices are shown ex VAT.
For small, slim items a white small parcel postal box can be a closer fit. Seal boxes with paper tape to keep the parcel plastic-free.
