My order was a small order of hardware. The order arrived well packaged, in a timely manner via US mail. I continue to receive excellent service from Military Fasteners. Thank You!

Nice online shop, with very fast operation and high quality service. A bit expensive and without quantity discounts but worth the money in general.
