Wood is a natural product that responds to temperature and humidity variations by expanding and contracting. Sometimes these changes may be noticeable in the physical appearance of the product. The conditions of your home can affect wooden products and your items can experience small movements and cracks as it adjusts - this is not a fault, but a natural occurrence within the fibres of a natural product. We advise you to keep the product in consistent, stable conditions to minimise the affects of temperature and moisture change in the atmosphere.
