My TWSBI ECO Collection + A FLEX Nib Experiment!

At your request, I'm finally sharing my humble TWSBI collection with you all! 🩷 I'm also showing you my latest little tinkering experiment: fitting Fountain Pen Revolution #5.5 nibs into my TWSBIs. They're definitely not a perfect fit... but wow, is it fun having a flex nib in a TWSBI! My TWSBI ECOs are probably the most fun pens in my collection. They handle difficult inks like champs, the cap seals incredibly well to keep the nib from drying out, and they're tough enough that I'm never afraid to actually use them. Plus, if I ever break a part while fiddle-faddling with one of them, TWSBI will send a replacement for the cost of shipping. That makes me so much more willing to experiment. The one thing I've always wished for is the ability to swap nibs as easily as you can on some other pens. That's what inspired this experiment. Unfortunately, the FPR nibs don't line up perfectly with the TWSBI feeds, so I can't wholeheartedly recommend it... but they're close enough that I'm definitely going to keep tinkering with them. So come along as I show you my TWSBI collection, the inks I've paired with each pen, and how this nib experiment is coming along. I hope you enjoy!
