Please e-mail me to discuss the services you seek before sending your shutter.
My preferred carrier is the U.S. Postal Service. Before shipping, remove the lens cells from the shutter and remove the shutter from the lens board. Be sure to enclose your name and contact information in the package and ship to:
Alphax Betax Shutter Services
4005 Wisconsin Ave NW #5598
Washington, DC 20016
All return shipping is via USPS Priority Mail with signature confirmation and each shutter insured at these default replacement values. If you would like additional insurance or other services, please let me know.
