Thank you for viewing! (^_^*) This is a listing for magnetic tees. This product includes long tees (80mm) & short tees (35mm). Similar to Bridgestone's MAGNET TEE, the stake that is inserted into the ground and the tee head that holds the ball are connected by a magnet (@_@) The magnetic connection separates upon impact, so there is no resistance from the tee, allowing for a smooth swing, which contributes to improved distance and accuracy ( ´ ▽ ` )ノ Also, the stake and the tee head are connected by a nylon string, which reduces 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 a request. 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 will take a look (^_^*) 〓Product List〓 #kuu-shop golf competition driver slice draw distance golf
