In this day and age, it is rare to be impressed by customer service however, Military Fasteners has far exceeded my expectations. They went above and beyond to help ensure an important package delivery on time, and they made a little boys Christmas sweeter in the process. Thank you to the team there for your wonderful help. I will certainly come back to shop again and again. They always say, fly people are the best people.

Tanks for the fantastic service. I ordered over the new year period and was amazed my shipment arrived so fast, all the way to New Zealand. Less than a week and that included clearing Customs. Awesome!!
