🔍 Detailed Impressions
First impression: is this really a pen?
It's an intuitive concept — an ultra-slim pen that looks like a card. There's a clear philosophy behind it: a simple structure, refined finish, and the idea of "eliminating anything unnecessary." It feels less like a writing tool and more like an object of design.
Why I haven't bought it yet
The price is a burden: At ₩342,000, this is quite expensive for a pen. I appreciate the design and originality, but when I think about practicality, it's hard to pull the trigger.
Doubts about practicality: Having to transform it from a card into a pen every single time you want to write seems like it could get tedious.
Still, here's why it's appealing
Distinctive design: It breaks away from every preconception of what a pen should look like, and that's genuinely appealing.
A Korean brand: Knowing it carries Korean design philosophy and craftsmanship makes me want to root for it.
The finishing piece of an EDC setup: For anyone into EDC, this feels like it could be the perfect addition.
