Common questions
How many times can these envelopes be reused?
The 28 lb. kraft paper and reinforced string-button closure system support 15-25+ internal circulations per envelope depending on handling. This reusability significantly reduces per-use cost compared to single-use envelopes, typically delivering 40-60% cost savings over 12 months.
Are these envelopes USPS compliant for inter-office shipping?
Yes, these envelopes meet USPS requirements for inter-office and intra-company mail. The 10 x 13" size fits standard postal regulations, and the pre-printed routing format supports proper address formatting and delivery verification.
What happens when all 52 entry lines are filled?
Once filled, simply reset the envelope back to the sender or mail room for line erasure, or retire it for recycling. The kraft paper surface is erasable with standard pencil erasers, allowing indefinite reuse cycles without replacement.
Can these be customized with our company logo or department names?
Yes, we offer custom printing options for bulk orders (contact sales for minimum quantities). Pre-printed versions ship within 5-7 business days, while customized designs typically require 10-14 business days for production and delivery.
