This Disc: Light Blue Foil Stamp

New Release: Stock Stamp Sten (K4 Plastic)

The Stock Stamp Sten is here—marking the first time this mold is available beyond the limited first run. Now produced in Kastaplast’s brand-new K4 plastic, this release brings both visual appeal and performance to the next level.

K4 is a hybrid blend that sits between base and premium plastic. It has a soft, flexible feel with extra grip and gumminess, which not only gives it great hand feel but also makes it float in water—yes, it still floats. The wear will show, but the flight remains consistent, making it ideal for touchy approach shots or low-power lines.

Whether you're adding it to your bag as a trusted utility option or handing one to a new player as their first disc, the Stock Stamp Sten in K4 is built to be fun, functional, and durable.

This isn't just a reissue—it’s a refined launch of a unique disc that stands out in both feel and function. If the first run was your intro, this is the one to stock up on and share.
