Demei Floating Pen Tilt and Float Ink Nib Sketch Pens with Washable Ink  (Set of 8, Multicolor)

A floating pen, also known as a floaty pen or a float pen, is a type of novelty pen that features a transparent barrel filled with liquid, usually water or oil. Inside the barrel, there is a small, buoyant object or scene that moves or "floats" when the pen is tilted or turned. This object is often a miniature figure, logo, or a scenic element that glides from one end of the pen to the other, creating a dynamic and engaging visual effect. Floating pens are popular as promotional items, souvenirs, and collectibles due to their unique design and the mesmerizing movement of the floating elements. They combine practicality with a playful aesthetic, making them a delightful addition to any stationery collection.
