A pack of 25 brown 'Sumo' C5+ mailers with tough brown paper coating a light lattice of grey paper, made from 100% post-consumer waste. These measure externally 235mm x 265mm, or internally 216mm x 265mm. The adhesive on the peel & seal closures is animal product-free, so these are suitable for vegans. These bags confer excellent protection, but are lightweight to keep postage costs down. Manufactured in Germany. Other sizes available on request.
