Thank you for viewing! (^_^*) This is a listing for magnetic tees. This product is a set of 10 long tees (90mm). The tee height is approximately 50mm. Similar to the Bridgestone MAGNET TEE, the stake that goes into the ground and the tee cup that holds the ball are connected by a magnet (˃̵ᴗ˂̵) The magnetic connection separates upon impact, allowing for a swing with no tee resistance, which contributes to improved distance and accuracy ( ´ ▽ ` )ノ Also, the stake and tee cup are connected by a nylon string, reducing the chance of the tee flying away and getting lost! This is also a cost-effective product. These tees conform to golf rules, so they can be used in competitive golf! The quantity can be adjusted depending on the stock, so please let me know in the comments if you have any requests. I also have many other golf goods for sale. If you leave a comment, I can offer a discount and list them as a set, so I hope you'll take a look (^_^*) 〓Product List〓 #kuu-shop golf competition driver slice draw distance golf
