TWSBI Diamond 580, a classic fountain pen with a piston ink-filling system. By fusing the traditional mechanisms of the fountain pen with a modern industrial design, we have created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present. The Diamond 580 comes with a benchmark ink-filling mechanism and has all detachable parts. We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.

 

Additional Description

The idea behind the TWSBI Diamond 530, 540, and 580 was to go back to basics and capture the simplicity and elegance of traditional writing instruments. In recent years, the development and modernization of writing instruments has resulted in traditional writing instruments, such as fountain pens, falling into obscurity. It was our goal to bring the past back to life by creating a traditional fountain pen that even modern day society can appreciate.

These are my favorite underwear! They cover my c section pouch and they are really soft and comfy. They're stretchy but they're also supportive.

Excellent Value
Color: Black - Set 3, Size: 5X-Large
I love these briefs! They fit perfectly according to the size chart, and are extremely soft and comfortable yet also help firm you just a bit. The crouch is large enough that a pad fits without hanging over the sides. They are also well-made and an excellent value. I cannot speak to durability yet, but I cannot see why they would not last. I will definitely be buying more!

this is my go to when needing new underwear.
Size: 3X-Large, Color: Black/Navy/Dark Purple/Red
Love these boyshorts for women. They're so comfortable, no crawling and breathable. I recommend for plus size women who has legs rubbing together causing irritation. Nice price as well. This is my go to when needing new underwear.

Great!
Size: Small, Color: Black/Heather Gray/White/Nude
Comfy, good fit, good quality cotton and flat seams around the crotch. Normal size small. I wouldn’t wear these with yoga pants, but nice under looser fitting garments. I would buy more colors.
