Each piece of the Asli Arts Angel Capiz 30 in. Wind Chime is hand-sorted in Bali, dried, sliced, shaped, sanded, and dyed to create a one-of-a-kind work of art for you. Skilled craftsmen then string the capiz together with invisible nylon cord. Though every part of this product is weather-protected, we recommend a few simple maintenance tips to keep it looking its best for years to come. Simply apply a thin layer of Danish or lemon oil to hardwood parts periodically. Regular application of oil will slow down the natural aging process of wood. Mild soap and water clean the capiz.
