Hand wash and dry before initial use.
To wash: use gentle soap and rinse completely.
To store: keep in an area that has a consistent temperature, as wood will naturally swell and shrink in extreme temperature changes.
To care: use a natural oil (like grapeseed) to season wood if desired, and to avoid cracking over time.
Note: liquids that stain easily, such as red wine, could change the interior color of the cup. Avoid boiling water and other extreme temperatures. Not dishwasher or microwave safe.
