## Customer feedback

Customer feedback highlights use for paycheques and invoices and appreciation for the envelope thickness. Some report adhesive that does not hold adequately, and others criticize the window as too low or inconsistent. Opinions on sealing, durability and ease of use are mixed. These reports matter for high-volume mailing, especially when the document must align precisely or a seal must hold consistently. The overall rating distribution is mostly five-star, but aggregate ratings do not establish how reliably every envelope seals or aligns.

- Negative themes: Some customer feedback reports inadequate adhesive and window placement that is too low or inconsistent.
- Mixed feedback: Customers express mixed views on sealing, durability and ease of use.
