This slim, portable design allows you to practice anywhere. Do you ever find yourself practicing putting on a crowded golf course, having to be mindful of others? As someone who is shy and introverted, I used to feel hesitant about joining others in aiming for the cup. That's why I created this tool that allows you to practice putting even in the corner of the practice area. It's a thin, portable design that can also be used at home, making it a win-win. I found it so useful that I'm now selling it. If you're in the same situation, please consider purchasing it! And even if you're not, please do! This tool helps you check if you're hitting the face straight. The opening width is approximately 50mm and approximately 59.5mm, and the height is approximately 49.5mm. Balls and tees are not included. This is the price for two black practice tools. You can practice slowly at home or in the corner of the course's putting green when it's crowded. It stands on its own by inserting a tee, making it convenient to carry. However, it may wobble slightly. * When standing with a tee, it will be slightly tilted, so the opening height will be about 5mm lower, but the ball can still pass through. You can also use the notches to stand it up and use it as a target, or lay it flat and use it as a substitute for a cup. Due to being a 3D printed product, it has unique layer lines. Please be aware of this. Other items are also available. #Jun Item...Putting Practice Tool
