Monteverde is part of Yafa company. Some time ago the company offered wide array of new inks with Ink ITF™ - new Ink Treatment Formula that's supposed to drastically improve ink-flow quality, extend cap-off time and improve ink drying time on paper. After trying two inks I can agree it's not just marketing - the inks behave very well.
New colors are divided into two series. The newest one is called GEMSTONES.
I admit I have a problem with this name as Pelikan started their Gemstone collection (Edelstein inks) years ago and was succesfull. I do realise that this name can't be copyrighted but I feel something's off. Sure, it's easy to base marketing on proven and succesfull ideas but I feel just a little bit of disapproval. I believe they could have created something new, especially that the colors are rather interesting and eye-catching.
Anyway the line has inks
I appreciate the fact that Monteverde posted on their website data about these inks ph:
The inks can be bought in 30 (and 90) ml bottle. The bottle is made of lass, has simple design and id pretty functional - stable and with wide neck allowing to fill quite comfortably (as long as there's more than 60 % of the ink content in it) evem monster fountain pens straight from the bottle.
The ink is strongly saturated. It's a killer blue actually - intense, strong, vivid. Also, it behaves well. I would say that if you look for well behaved and strong blue ink, lok no more.
Thank you Nikaa for allowing me to fill TWSBI 580 with this ink
