I purchased this as a spare because I started using a cane and had difficulty walking. I used one myself, and surprisingly, it didn't wear down much and lasted a long time. It's new and unused. The description says, "Non-slip rubber ideal for rainy and snowy days, 16mm diameter for improved stability," and my personal experience is the same. - Brand: SINANO - Type: Non-slip safety tip - Diameter: 16mm - Color: Black - Condition: New, unused - Uses: Rainy days, snowy days, wet sidewalks I will ship using your preferred method within the possible range. Multiple items can be shipped together. Returns are not accepted after purchase. Thank you for looking.
