BAMBOO: Treat bamboo like you would wood. Do not leave it in rain or harsh sunlight. Covered balconies and outdoor sit-outs are fine. Cracking in bamboo is completely normal, as it is a natural material, and it generally won't affect the structural integrity. We are happy to repair and repolish your piece for as long as you own it, on request.
BRASS: Clean with a moist towel and dry promptly. Avoid direct heat or sunlight exposure. Polish as required.
