A4 Dry Erase Pockets Double-Edged PET Set

These reusable dry erase pockets are sized to fit standard A4 paper (21 x 29.7 cm) and constructed from clear, rigid PET film with consistent 0.15 mm thickness. Double-edge sealing ensures structural integrity during frequent handling and repeated insertion/removal of worksheets. Each sleeve features a top-mounted metal grommet for easy hanging on boards or hooks, plus a recessed pen holder to keep the included dry-erase marker always within reach. Ideal for interactive learning: students write directly on the sleeve over inserted content, then wipe clean and reuse endlessly — perfect for maths drills, spelling practice, vocabulary revision, and formative assessments in UK primary and secondary settings.
