Beiner Bags is a family owned and operated company that make some of the best cases on the market. We use only the highest quality materials and take pride in manufacturing each and every bag by hand right here in the United States. We are all professional musicians and case makers with over 30+ years of experience in the sewing industry. So we know the exact quality that is needed and expected in the busy life of a musician, whether that be a student or professional. Our cases are made out of 1000 Dynamite Denier nylon, which is some of the strongest material on the market and used in military grade bags. The interior is lined with a sleek and durable rip-stop nylon, which is the same material used in high end tents and outdoor wear. Every case has .5"-1" high impact foam throughout, keeping your instrument just as safe as some of the plastic cases on the market. We also use durable metal rings and clips for our shoulder straps. You paid good money for your instrument and want it to last for a long time. So why not use a high quality, hand-made Beiner Bag to protect it! Since we make everything in our sewing shop in Florida, we can do all custom work as well. So if there is something you don't see, or something you would like to add to the bag (like a cool color) just let us know!
