Pilot Refill for G - Tec C4/Maica 0.4 mm - Black

Excellent product - my favorite pen bar none. Fits the original casing perfectly. Come individually packed in a plastic sleeve and with a plastic tip to ensure they don’t dry out. Cuts the cost of buying the full pen and limits plastic waste

Work well. Individually packaged, so a lot of plastic which is a shame, but the three I've tried so far work fine, are not dried up, so very happy.

Exactly what I needed, arrived in good condition and work well, decent price for this product.

Excellent idea. Being able to buy refills is fantastic for the planet. Hey are just as good as the ones coming in the pen.

Work perfectly just sometimes they release a bit too much ink respect to the original pen.

These are the best fineliner for those who don't like the sort that get a flattened tip with use. These stay fine and smooth flowing til the very end, and I have used nothing else in its place for years and years, both for art and writing. The pack of refills is good value and convenient, it will last ages. If you've not used a G-Tec C4 yet, do, they are a joy to draw with!

The genuine refills which can be purchased from reputable sources are consistently of good quality, but these from Amazon are defective.The ink flow is inconsistent, either too little or too much, and the result is an unreliable writing experience with either ink smears or scratchiness.

Each ink is packaged in a protective bag. The quality is as it should be.
