Designed in 1991, the Sewlock™ zip security chamber is still the only chamber of its type available — worldwide. Its uniqueness lies in its ability to either seal or lock the chamber via a padlock or a variety of ‘one-time-use’ seals.
All our mailing satchels carry the Sewlock™ zip chamber. Discounts available for 50 + units.
