These tips are the same as the sturdy long lasting 18mm steel inserted tips but has a fun checkered board pattern which is meant to mimic the mesh pattern on the carbon fiber canes. These tips are made with a steel washer which reinforces the tip to make them stronger and more durable against wear and tear on rough terrain. Accent any 18mm carbon fiber cane or any other 18mm cane with these decorative black tips. This rubber tip is non marking so unlike most rubber tips it will not leave black marks on floors.
