The Navy Blue JUUL battery will cost the same as the normal graphite color: $34.99. And like all other JUUL products, there are some rules: Only 3 Navy devices per customer per month. The big question is, how many months will it be available? Will it even be available after a month? Since it’s a limited edition, jump on it now if you want one. It’s unknown how long this will be available or how many were made.
