Extra Strong Magnets for Whiteboard, Glassboard and Fridge (White, 8 Pack, Small). N52 Neodymium Rare Earth Heavy Duty Magnets for Home and Office Supplies.

• STRONG MAGNETS -- These are N54 neodymium (rare earth) magnets, the strongest on the market! The higher the grade (the number following the 'N'), the stronger the magnet. This one uses the highest grade for maximum performance.
• HOLDS UP TO 30 PAGES -- Easy to remove but with enough power to hold up to 25-30 pages on a whiteboard or fridge and up to 4 on a glass board (but not suitable for glass craft mats). That's strong enough for one magnet to hold up your calendar and notes on your kitchen fridge!
• IMPACT RESISTANT -- The outer shell is not bulky but made up of very tough, impact-resistant polycarbonate plastic that is over 200 times stronger than that cheap acrylic plastic seen in other magnets.
• DESIGNED TO LAST -- The magnets are thick for proper mechanical strength and are coated with a triple layer of nickel, copper and nickel again to prevent rust. Buy it for life.
• FINGERNAIL FRIENDLY -- These magnets are easy to grip, so are super easy to move around thanks to the finger-friendly plastic shell. Great magnetic power remains easy to control and avoids injury.
