For the longest lasting bar, we recommend that soap bars be placed on a perforated tray and allowed to completely dry between uses. This bamboo holder is perfect for this job. Bamboo is an abundant, sustainable resource and is naturally resistant to mold. Holders measure 3.3 in x 3.3 in x 0.67 in fits all of our bar soap. For orders of $50 or more, you will receive this bamboo holder and shipping for FREE! No need to purchase this item if you are ordering more than $50 worth of handmade products (chicks and hatching eggs excluded).
