Disclaimer – Please Note
The pieces I make are decorative/ornamental and are not waterproof or food safe. Colours may change over time.
Wood is a natural product - there could be further movement depending on the environment it is in, to me this can enhance the piece, but I understand not everybody will like this. 
 
Wood can experience dimensional movement with temperature changes.
Wood can expand and contract as it is exposed to moisture and changes in different climates.
Wood can change colour with the natural aging process and with exposure to light & oxygen.
Keep out of direct sunlight
