RV Soap Holder

Made this soap holder to keep it from making a mess when I am driving. So mostly a RV holder if you have something magnetic near by or can use a washer screwed to the back splash. Inside there are two cut outs for 12mm X 3mm magnets. I ordered them from amazon here is the link. https://www.amazon.com/gp/product/B01LYEJFK3/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
