Pilot 43600 1 Ounce JUMBO Marker Refill, BLUE

This is a repurchase of the same ink. It is well priced and goes a long way. The ink well lasted the whole school year in my classroom. The only negative is that the plastic dropper is tedious to use and it was easier to just pour into my permanent marker. It can be messy as well and stains the hand for a bit.

good refill ink.

This is the best ink to put in a drip mop! you will get nice drips! if you add some nail polish remover it stains better than Smash KO.

So far, so good. I've refilled my blue Pilot Jumbo marker once with this ink. I like that the ink is in a glass bottle/jar with a screw top cap. The instructions indicate placing "a few drops" of the ink to refill the marker, but it takes much more than that - more like several droppers full - for the jumbo markers, anyway. But there's still plenty of ink left in the bottle after the one refill. Based on the amount of ink I used for one refill, I estimate that I'll get at least 4 or 5 more refills out of it, which is a good value at approximately $1/refill when the markers are $4-$7 each. The only reason I took one star off is the strong odor. The instructions say to do the refilling in a well-ventilated area. I did it outside.

Good quality
