APO/FPO OVERSEAS MILITARY CUSTOMERS: USPS REQUIRES 18650 BATTERIES BE SOLD WITH AND INSTALLED IN DEVICES WHEN SHIPPED OVERSEAS.
TVB will not ship THESE BATTERIES without the PURCHASE OF A DEVICE IN WHICH THEY CAN BE INSTALLED PRIOR TO SHIPPING.
We can install/ship batteries in mods but they cannot be sold/shipped without devices. Please email us with any questions at info@thevapingbuddha.com (Note: Some countries have additional restrictions on li-ion battery shipping; please contact us with your shipment country for further details.) Thank you for your service, and we apologize for any inconvenience.
