   FAQs

What's The Purpose?

At its core, the Zivii Loop String is about fun and interactive entertainment. Using advanced engineering and the laws of physics, it delivers an immersive, gravity-defying light show that engages the mind and makes it hard not to smile.

 

Beyond entertainment, the Loop String is great for brain stimulation and stress relief, it makes an awesome fidget, a top tier cure for boredom, an incredible dance accessory, a hilarious cat toy, and even crazier things like a tool for lightpainting photography.

 

It’s an all-in-one gadget that delivers a dynamic, interactive experience for all ages.

How Does It Work?

The Loop String operates on the principles of physics and expert design to float effortlessly in the air. At its core are two high-RPM brushed steel motors that spin at over 20,000 RPM and nearly 40 mph.

 

This speed generates the necessary momentum to counteract gravity and lift the string into the air to trace your movements, defying gravity and delivering a mesmerizing levitation effect.

 

The built-in 365nm UV blacklights further enhances this experience by illuminating the fluorescent strings, creating a glowing light show that’s perfect for low-light environments.

Is the Zivii Loop String difficult to learn? 

Not at all! It's designed for all skill levels. While mastering advanced tricks takes practice, beginners can create amazing effects within minutes.

How long does the battery last?

The USB-C rechargeable battery provides 2-4 hours of continuous play.

Is it safe for children?

Absolutely! The intelligent power cutoff system automatically stops motors if the strings tangle, making it safe for ages 8+. Always supervise younger children during play.

What makes the strings glow so brightly?

 Our Zivii™ strings are specially formulated to react with 365nm UV light. The dual blacklight system creates maximum illumination for stunning visual effects.

Can adults enjoy this too?

Absolutely! It's popular with all ages. Many adults use it for stress relief, creative expression, light painting photography, and as a unique conversation starter.

What if it breaks or doesn't work as expected?

You're protected by our ZiviiCare+ 100-day warranty and money-back guarantee. We stand behind our products with exceptional customer service.
