I like this pen but I don't think the flex nib is working. I'm not getting the thick and thin lines that I want. The image I uploaded shows the constant size line I get. Definitely it's the flex nib that I'm using. I sent messages to you vis the website 3 times over the last two weeks. This is not the customer service I expect. Is this some kind of scam? could someone help me get the flex nib working as I need it to work? Thank you.
Like the flex nib….
As a music teacher, I need a pen that feels balanced in the hand for marking up sheet music. The XV Nusa sits beautifully on my piano, and the "Executive Vibe" branding is spot on. The XV Flex Pro Nib made a huge difference for anyone in the art space!
I’m a stickler for handwritten Christmas cards, and this smoky XV Nusa is a dream. It looks so sophisticated paired with my holiday journals. The XV Flex Pro Nib is the best in the industry! It makes the act of writing feel like a celebration.
I’m already prepping for the new year, and the XV Nusa is my new daily driver. I’m a "planner addict," and I need a pen that can keep up with my rapid-fire to-do lists. It’s comfortable for long writing sessions, and let’s be honest, it looks great on my desk next to my snacks!
I use this pen specifically for my morning study and reflection time. The blue resin is stunning, and it glides across the page effortlessly. It feels substantial and helps me stay focused while I’m taking notes on important life principles. Solid 5 stars.
I couldn't wait until the 25th to open this! The Transparent Blue looks like a sapphire ornament under the tree lights. The presentation box is high-quality and makes it look far more expensive than it actually is. If you have a writer in the family, stop looking! This is the gift.

I bought the XV Nusa Forest to match my guinea pigs' favorite snack, romaine lettuce! I use it daily to log their feeding schedules and weights. It’s incredibly lightweight, and the ink flow is so smooth it doesn't skip even when I’m writing in a hurry before floor time. A fun, vibrant tool for a busy pet parent!
I spend 10 hours a day on my Mac, but I still believe in the power of the handwritten note. XV Nusa Forest adds a perfect pop of color to my otherwise grayscale desk setup. It’s sleek, modern, and the screw-cap feels very secure. It’s the perfect bridge between my tech and my tactile thoughts.

Holds ink well, writes consistently, and looks elegant on my desk. Perfect combination.
I’ve been using it daily for work and classes—never once had an ink burp or skip.
The transparency sold me, but the comfort and flow made me a fan. Excellent pen overall.

Writes smoother than some of my gold-nib pens. Truly impressive.
Easy to clean and even easier to refill. The engineering shows in the simplicity.
Light, balanced, and always ready to write. I use it for both sketches and notes.
The cap threads feel refined, not scratchy. Small detail, big difference.
Watching shimmering inks settle inside the barrel is beautiful. Perfect for ink lovers.
