TWSBI Diamond 580 Smoke Rose Gold II Fountain PenTWSBI fountain pens are beloved for their clear barrels (sometimes called demonstrators) that allow users to see the ink inside. The barrel of the pen features a faceted design, which allows it to stay in place when you set it down on a flat surface. The pen has an interior ink filling piston system that holds much more ink than a typical fountain pen cartridge. It also allows you to fill your pen up with ink without the use of a converter.

My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Great quality

Fit Type: Boyshort, Size: X-Large, Color: Assorted Colors

⭐️⭐️⭐️⭐️⭐️ Super Comfortable and Great Fit! I absolutely love these Hanes seamless boyshorts! The fabric is soft, stretchy, and doesn’t dig in at all. They stay in place perfectly throughout the day—no rolling or riding up. I love the mix of neutral and soft colors in the pack, and they hold up really well after washing. Perfect for everyday wear, lounging, or even under leggings since they don’t show lines. Definitely worth the price—will be buying more!
