Top level product But don't store for a long time

On time delivery

Very smooth and writes perfectly. Color is great

They do the job and they don't leak, which was a problem in tactical pens that don't write much.

Estou muito satisfeito.

the one i received leaks a lot! ruined my scrub suit! i complained and amazon accepted the return

Perfect ink. Does not skip. Much cheaper than other brands, though their quality is much better. These refills fit my Rotring 600 ballpoint/gel pen perfectly, so I believe they are compatible with whatever pen uses a standard G2. I mainly use these refills in my Rotring 600 but I leave a bunch of these refills everywhere to use as a quick pen; they’re very versatile - so small and easy to keep everywhere and anywhere. I have one or two in my purse, car, pocket, etc. at all times. Only issue - if you have large hands like my husband, it’s difficult to use them as is (not inside a pen); but I don’t have that problem. Beautiful blue ink; fully saturated and dark black ink. The quality is better than any other ink I’ve purchased. Drawing; writing; this ink makes me want to use paper instead of my iPad.
