Magic Tail Cat Gel Pen 0.5mm Black Ink DIY Assembly 4 Pack

DIANSHI DS-045S Magic Tail Cat Pen 0.5mm Black Gel Ink — Wiggling Cat Tail Click, DIY Assembly, Set of 4

Click the pen. Watch the tail wiggle. The DIANSHI DS-045S Magic Tail turns the simple act of clicking a pen into a tiny moment of joy. Each pen features a miniature cat figure perched on top, and every click makes its tail bounce and sway — a playful fidget mechanic built right into your writing tool. This DIY assembly version lets you build each pen yourself, mixing and matching parts for a hands-on unboxing experience before you even start writing.

How the Magic Tail Works

The cat's tail is connected to the pen's click mechanism through a spring-loaded linkage. Press the clicker to extend the pen tip, and the tail springs to life — bouncing, wiggling, and swaying with each click. It's a small, satisfying motion that makes this pen impossible to put down. Part writing instrument, part desk toy, entirely addictive.

DIY Assembly: Build Your Own Pen

Each pen arrives as a simple kit of snap-together components. Assemble the barrel, insert the ink refill, attach the cat figure and its springy tail — done in under a minute, no tools required. It's a fun tactile experience for kids and adults alike, and it makes this set an ideal craft activity, classroom reward, or party favor. Four pens means four builds — perfect for a rainy afternoon or a group activity.
