EZ WINTER GOLF TEES. Printed in carbon fiber, 100% infill. Screws into the frozen ground with ease and works GREAT. REUSE BROKEN TEES with the INSERT. I used super glue to bond the top and bottom together. I removed the original bottom and insert FILES, as I found the length of the thread was not necessary. If you would like the original FILES relisted, just send me a message. Thank you for viewing and please visit my other listings
