Some may wonder whether the end caps are treated with either oil and/or some kind of varnish. They aren't. Purposefully ! They have been precisely cut, machined and fine sanded but left on without any treatment. We believe that over time, the natural oils secreted from your hands will polish the wood which in turn will take its own unique patina. Every end cap will be uniquely different and should last for a very long time. Some of you may want to use some Wax with extended use, however please be aware that this may cause the wood to darken. If you are purchasing the MYT Glide SMALL and are sensitive to the Aromatic Cedar end caps, let us know, we'll forward you a new set treated with a natural product that will take away the smell while preserving the fine wood color and grain.
