A 3-hole Indoor Practice Putting Green

The item is essentially rolled-up in the box, as I haven't even opened it yet. It was for my dad, but he didn't want it 🥺. Basically, I'm just trying to get my money back for it. In all honesty, I've had mine for several years, and it does help you hit straighter putts with better speed. In other words, it should help you lower your score, as most people struggle with their short game the most...
