uniball™ 207 Plus+ ゲルペン、ブラックインク、0.5mmマイクロポイント、4本。

These pens are just the best! Smooth and easy to write with and I love the fine 0.5mm tip. The grip of the pen is comfortable and easy to use.

Quality pen. Smooth handwriting comfortable grip. Recommended by security expert Frank Abignale for combating check fraud. Highly recommend!

Writes smoothly with wet ink. As satisfying as using a fountain pen. Dries almost instantly. Ink melts into the paper it is written on and as such cannot be removed by fraudsters “washing” out the ink. I bought this pen for the fraud proof feature but find I enjoy the feeling of using wet ink.

Great product for preventing fraud by washing checks or other documents to enable making changes. It does work well enough that marks accidentally made on a piece of clothing will wash out. Also useful for labeling T-shirts etc. on a hem or other location in case they get mixed with other's laundry.

Same writing and ink quality as ones I purchased before. I have only used 2 out of this pack and so far no leaks.
