PILOT ドクターグリップ 4+1 多機能ボールペン替え芯 細字 ブラック/レッド/ブルー/グリーンインク 3本パック

the refills are less expensive than a new pen and work just as well. Good product.

J'ai bien reçu cette commande. Comme d'habitude j'envoie une évaluation . Merci Micheline Guillemette

Great refills for a great pen.

I am hooked on the Pilot Dr Grip 4+1 pen. Having piles of refills really helps. I take a notebook almost everywhere and write notes constantly. The .7 mm is perfect. But I run out of ink often while writing. So having refills in my backpak is very convenient. It almost never smudges.

I do a lot of annotation and explanatory diagrams, and have got myself in the habit of carrying and using 4+1 multicolor pens. The Dr. Grip body is my favorite on the market (and at this point I've tried 7 different options), and the Pilot refills are my second favorite. The Uni Style Fit system offers the second best body, and my favorite of the refills. Fortunately, the two are compatible with each other's refills. As much as I like the Uni Style Fit refills, these are substantially cheaper and longer lasting, and slightly less prone to smearing, but they give a little more drag when writing, and the colors aren't quite as vibrant. I've alternated on which I use. These are certainly fine to keep an Dr. Grip 4+1 in action.
