“I absolutely love the idea of Jumboer Coin.”

Hello everyone, I’m Jeffrey Wang. Happy New Year! Happy Lantern Festival! Happy Birthday! Happy National Day! Long time no see!

Whether you’re an enthusiast, a professional magician, or someone completely new and curious about magic, I’d like to introduce you to my latest magic prop:

The “Jumboer Coin,” also known as the “Flash Giant Coin.”

Eighteen years ago, I first encountered coin magic: I held a tiny coin in my hand, and my magic journey began.

Thirteen years ago, I first saw a jumbo coin in a magic shop—and I was absolutely stunned.

Back in high school, I used to sprint to that magic shop after class and stay for hours. The shop owner, Mr. Ge, barely noticed me—I’d quietly browse through all the props while he watched TV. That shop, which was the starting point of my magic career, is long gone—but it sparked my childhood magic dreams. One day, I discovered a collapsible, foldable elf hat there and had a lightbulb moment: “Can I make a jumbo coin that folds and collapses, too?”

That idea stayed in my head, and ten years later, I finally made it a reality. You may have seen similar items—photography reflectors or those foldable mini fans—they all use the same collapsible principle. So I worked with a manufacturer to produce a batch of half-dollar-sized props featuring Kennedy’s portrait—that became the Jumboer Coin you see today.

Here are the specs: the set of Jumboer Coin includes one prop. It pops open instantly. When fully expanded, it measures 25 cm in diameter. When folded, it shrinks to roughly one-third its size.

Wishing you happy practicing and lots of magical moments!
