Kastaplast's Description:

This easy-to-use disc might be your secret weapon to perform the lines you need. However, don’t mistake it for a beginners only disc. Whenever you need massive glide, Svea will deliver. It offers a lower profile than our Göte midrange disc, making it suitable for smaller hands. Easy to grip and easy to release. Svea is an old Swedish name which is derived from the people of Svea Rike, later Sweden.

Suitable for: Low power throwers and whenever glide is needed.

K4 is a hybrid plastic blend that sits between base and premium in both feel and durability. It has a soft, grippy texture with a slightly gummy flexibility that adds confidence in the hand. While it will show wear over time, the flight remains consistent. K4 also floats in water, making it a smart choice for casual rounds, warmups, and catch discs.  

Since K4 is very soft and flexible it bends and marks easily.  Minor scuff marks on this plastic can be common from regular shipping and handling and often come that way from the manufacturer.
