Grym is Swedish for cruel or awesome... like the sport itself, it can be both. The Grym X (standing for xtra stability) was designed for experienced players looking for a solid main driver. This disc will give you that distance you're craving, over and over. It's a great combo of speed, accuracy, and glide. It's a fast disc that's still easy to grip. Available here in some of the best glow on the market. Glow Kastaplast tends to be more understable than Standard K1 plastic.
The story behind 'Flies Just Fine' stamp - Earlier this year they had to cancel all K1 Glow Grym X orders after they discovered that they have a blister on the sprue which could be peeled. If you pick and pull the blister repeatedly, you should be able to peel off a small circle of plastic. These discs have now been stamped with a second stamp "Flies Just Fine" to indicate they are X-Outs. They Fly just fine and get them for a good price!
