This is a soap dish made by another etsy seller. You may find these under Gifts with a handmade washcloth and soap, as well.
These "wood soap dishes are handcrafted in South Bend, Indiana from 100% natural wood. They are designed with slots to drain water away from your bar soap and out of the dish. This allows your soaps to dry more quickly, and last longer."
And right now, if you purchase 5 or more full sized bars of soap, you will get one of these soap dishes free in your order.
The dish is right at 4" wide, 3 5/16" deep, and 5/8" tall.
