Ballpoint, gel & marker resistance
While permanent markers remain a challenge, the nano shield gives you a critical window of 1–2 minutes to wipe up most ballpoint and gel inks before they bond — and most fountain-pen ink simply rolls off.

Wipe within 90 seconds for spotless results
Ideal for study rooms and office chairs
