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 dry erase markers ROCK! Once you're used to the larger diameter shaft, they are super easy to use. The cap posts with a satisfying click. The chisel tip last 3 times as long as any regular-brand marker one would purchase. They are extremely easy to refill, but that is the rub. It is extremely difficult and expensive to get any refillable liquid for these pens. There are many PERMANENT ink cartridges available but NOT dry-erasable inks. Pilot needs to do something about this, hence the 4-star rating vs. 5-stars.

Easy to write chisel tip, long lasting ink at an affordable price
