Material: Red Palm (a.k.a. Coconut) - from Southeast Asia

Red Palm (or Coconut) is beautiful and easy to identify. Its grain is striking, and it's very lightweight.

These double-flared plugs are about 11mm  or 0.4" long in small sizes (up to 00g) and 1/2" long in larger sizes (7/16" and up).

Onetribe's Materials Care Statement:

Woods are more susceptible to moisture and humidity than most other natural materials due to the physical nature of the material itself. The primary purpose of wood grain is to move water from the roots to the upper portions. Because of this, dried wood will always tend to want to absorb moisture and thus prolonged exposure to water or soaking in liquids should be avoided. Being worked and finished properly will definitely help to prevent the absorption but long term wear and use will inevitably lead to the grain rising. This is normal and can be remedied by gently sanding to remove the raised grain with at least 400+ grit sandpaper (and then progressively finer grits if you have them) and finishing by buffing with a soft cloth. Wood should be periodically oiled with jojoba, coconut or a similar natural oil, which will help maintain their moisture content and also give the added benefit of transferring some of that oil's health properties to your skin. Most woods will darken over time with oiling and wear.
