These are great markers and worth the slightly additional cost. The tips last longer than a conventional marker and the ease at which they can be refilled is superior to other refillable markers out there. The only reason I gave it a 4-star rating vs. a 5-star rating is because getting refillable, dry-erase ink is a challenge. Make sure you don't get the "permanent" cartridges or refill with permanent ink otherwise you'll be in big trouble when you go and write. Pilot, start making refillable inks that are easy to obtain and pour into an empty cartridge. Let's save the planet!

These are hands down the BEST whiteboard markers around, and I have tried ALLLL the brands (Expo, Bic, Crayola, Staedtler, Quartet, Dixon). Bright, vivid colours, clean, easy erasing, refillable (just wish the cartridges were easier to find/cheaper), the nibs last forever (and you can buy replacement nibs) and they awesome for teaching!!! 123Ink.ca please consider carrying the PURPLE whiteboard markers and ink as well!!!! Right now I have to order it from Asia on eBay.

great cost saving easy to refill

I wanted something with a big tip but not the chisel tip, this bullet tip one fits the bill.

Fonctionne tres bien, Merci

These are the best whiteboard markers; they're very legible and they erase easily.
