Avery Clear Heavy Duty A4 Sheet Protectors are designed not only to protect your papers but to show extra clarity of your documents. The special acid-free and archival-safe material provides a crisp view of your pages as well as durable protection which ensures your papers stay in top condition and the print remains on your pages rather than transferring to the sheet protector. Made from heavyweight, non-tear material with a multi-punched spine to fit 2, 3 or 4 ring binders for easy storage. Ideal for office, school or home use to keep your paperwork in order.
