SchmidtP8120 Short Capless Rollerball Refill Broad Point 1.0mm, Black, 2 Pack Blister (SC58133)

pros- high saturation with bold lines without having to put a lot of pressure in writing- smooth writing experience with no skipping, scratching, or grit- high quality ink with a removable end cap that allows you to refill with fountain pen ink!! (the viscosity might be a tad bit off, but I refill with Noodlers Eel Fountain pen ink which is slightly lubricated and close enough with this refill's ink)- long lasting performance in my retro 51 rollerball twist pen (which basically means that it's uncapped and exposed to air)cons- can be a little touchy if you're not careful; that is, this type of refill is not always the most stable in pressurized environments or extreme humidity IF the tip touches something adsorbent (e.g., airplanes, high altitude environments, arid environments, or tropical environments)...basically that means that if the tip is touching something, it better be writing and not sitting on your shirt

I purchased these to refill my Retro 51 Tornado. I like a smooth thick line so I opted for the bold point and am happy I did.At the cost of replacing a littie more often, I get an extra smooth and extra bold line that makes it a lot of fun to write.

Thicker casing then the "fine" tip ones so it didn't fit in the pen.

Love the short capless. Write beautifully and cleanly. Can lines can bleed and not be the cleanest sometimes. Still great refills

These leak, they have ruined a pair of pants and stained two quilts...terrible!

not well made

The latest batch seems to be more like a 'medium' instead of 'broad'. Please fix quality issues.

Muy buen trazo, habrá que ver cuánto dura la tinta pero hasta ahora muy bien, la uso en mi Montblanc para las firmas
