This is a Brand New Kastaplast 2022 Glow K1 BERG Disc Golf Putter 172 grams in unthrown condition. You get the disc in the picture or its twin. I picked these up at the 2022 USDGC.
Disc-White — Stamp-Gold
Flight specs: Speed 1 / Glide 1 / Turn 0 / Fade 2
Kastaplast Says: Berg is designed for distinct shots, where you don’t need to worry about the disc hoovering far passed the basket. The disc features an ergonomic thumb track which is prominent on the top side while not being noticeable at the bottom. This makes it feel very different from any other putter. Berg is Swedish for mountain.
Suitable for: Windy days, fearless putts and distinct approach shots.
Plastic Lines: K1, K2, K3.
