Kastaplast Sten – PDGA-Approved Catch Disc & Beginner-Friendly Thrower

The Kastaplast Sten is a super fun, PDGA-approved catch disc that doubles as a perfect introduction to disc golf. Despite its name (“stone”), the Sten is soft, grippy, and lightweight—easy to control and easy to love from your first throw.

Key Features

• Beginner-friendly: great for learning form, casual catch, and smooth field work.
• Lightweight floater: approx. 127 g for effortless glide and touch.
• Comfortable grip: puddle-top profile makes it easy to hold and release cleanly.
• Soft & tacky feel: holds in the hand even in cooler or damp conditions.
• Angle-holding flight: responds to your release—great for gentle turnovers and hyzers.

Flight & Control

No official flight numbers, but expect a straight-flying disc with a small, reliable fade at the finish. The Sten tends to hold the angle you put on it, making it ideal for learning hyzer/anhyzer control and shaping easy lines.

Plastic: K4 Glow - See all K4 Glow Discs
K4 is a soft hybrid plastic that sits between base and premium, the wear and tear will show but the flight features remain. It has an extra grippy, gummy feel and floats in water. Plastic that lights up in the darkness. Using a UV light is especially effective to obtain the best and longest lasting results. Glow effect will gradually dissipate over time and will need to be charged back up again.
