Onse Disc Golf Collection
Onse Disc Golf is an online museum for collectable golf discs. I've collected discs since late 2011. Onse Disc Golf collection includes a wide selection of Innovas discs from the past, circle stamps, protos, first runs, oop plastic, like CE etc. but my main goal is definitely old school Innova discs. You will find a very large set of old discs from here. Welcome to my site! I hope you enjoy your time here! -Jani Ikonen
