All of their timbers have been sealed and varnished, which helps protect them from water marking or staining. Buttonworks recommend an occasional application of a vegetable oil to help protect the timber. Buttonworks is committed to using safe sustainable materials, so we only use suppliers and components that have reached ecologically sound and safe standards. The core of our veneers is a ‘craft wood’ Green Tag Gold Green Rate Level A certified and meets strict safety and quality standards. We use several species of sustainably harvested Australian timbers eg. Blackwood, Mountain Ash, Jarrah and Myrtle. Each order we pack will include a variety of these. Every effort is made to ensure the wood we use is from a reputable source where programs are in place to reduce impact on the environment. We use veneers and not solid timber to extend the use of the tree.
