Hullo’s current stock of buckwheat hulls were grown in Montana and North Dakota. All our buckwheat hulls are milled and air-cleaned in North Dakota. Hullo’s high-quality 12″ Dunlap zipper is made by Dunlap Zipper Company, based in Dunlap, Tennesee. Hullo’s labels are woven and printed in Colorado and woven in New York. Every Hullo is assembled in and shipped from Duluth, Minnesota. Thank you for supporting American small businesses!
