The Postmark protects the contents from being cut or damaged. The Postmark 3056 removes from 0 to 3mm (1/8 inch) of the envelope edge. The sliced material are deposited in the waste compartment.
The Postmark 3056 will allow to stack approximately 100 envelopes at a time in the feeder. The 3056 creates a soft, feathered edge opening, which prevents paper cuts and gives easy access to the contents.
