Thank you for viewing! This is a rubber tip for a walking stick. I purchased it several years ago but have never used it. Inner diameter: 16mm Maximum width: 80mm This is a self-standing three-point walking stick tip, which prevents the stick from getting stuck in manholes or small grooves, reducing the risk of falls. It offers peace of mind with its flexibility and light weight, making walking comfortable. I have never used it, but I would like to sell it to someone who understands that it has been stored at home. Thank you very much!
