Hardware Innovation & E-Commerce Bridge

Game-Changing Technology, Maximum Flexibility

Built with professional-grade hardware and AI integration. Zero compromises, zero operational constraints.

Hardware Innovation

3D-Printed QR Code Clip System

Say goodbye to messy tape, handwriting, and whiteboard queues. Attach a modular 3D-printed QR code clip to the racket shaft at drop-off. The clip stays securely on the racket through the entire stringing process.

Zero Tape, Zero Paper

Clips snap onto the racket shaft, meaning zero tape residue, zero manual ticketing errors, and instant scannability on any smartphone.

Maximal Flexibility: Choose Your Workflow

Operate 100% digitally without clips, or use your own paper/tape ticketing. The clip system is completely optional.

Free Starter Pack

Every new registered shop receives a free starter pack of 3D-printed QR clips sent automatically to their address!

Viscoelastic Stress RelaxationStrings are viscoelastic materials. Over time, tension drops due to static relaxation (immediately after stringing) and dynamic mechanical fatigue from ball impacts. Monofilaments/polyesters lose tension faster than multifilaments or natural gut.
