I've been using these pens since at least 2015 and they are phenomenal.They write smoother than any other pen I've used (except for a silver ballpoint with refillable cartridges I cannot find again for the life of me, probably bought from Staples or something not Amazon), the ink is unbelievably permanent (it's so strong that if you spill tea on cheap paper with this pen's ink on it the ink won't bleed, won't budge, won't smudge, NOTHING) and best of all they're comfortable to write with.I personally recommend the needle point ones the most, these are standard style wedge point pens but the needle ended ones allow insane precision.The 0.7 mm (I think that's what these are) line width makes these pens especially satisfying to do hand writing with as well as artistic stuff.Don't bother using those cheap Pentech or whatever that other company is that competes with Dixon (papermate I think) pens, these are THE pen to use.
