📍301 Massachusetts Ave, Cambridge, MA is home to  The Popp Boutique, a Black-owned business. The business is occupied by two businesses, Mahogany Expression and Journey Within. You can shop for a variety of products at the Boutique, including apparel,  hair products, body oils  and crystals. The African Black Soap at The Popp Boutique caught me off guard. Locally excisable for price and quantity. The business has great personnel that is always willing to help, and the overall abundance of the store is warm and welcoming. Did I mention the range of merchandise?  With on-going sales. Hours of the store range from Wednesday to Saturday 11 a.m-7 p.m and 
Sunday 12 p.m- 6 p.m.
