They are made of robust, clear film that completely encloses the document and protects it from dirt, moisture, and wear. Each sleeve holds between 1 and approximately 100 sheets, depending on the paper thickness, and allows for a clear, tidy presentation of offers, project documents, or informational materials. The pack contains 50 sleeves and supports organized filing as well as the secure transport of important documents.
