Sakura Craft Lab Gel Pen Refill

Hard to find outside of Japan where I got my pen.

Love these Sakura refills, this is a gorgeous dark green, just enough green to let you know it's green, very nice.

I also love the Sakura refills because they are NOT glass smooth...they have some resistance when writing, for more control (for me, anyways, your mileage may vary). The ink is nice and dark, does a great job on most any paper. If I leave one sit too long, the very first stroke may be rough, but it goes right away. Can't say enough good about these refills, love them! I wish they made one to match my new yellow Craft lab pen!
