SHIPPING: Usually for many countries, I send the Hydrophone through ECO
POST which guarantees the delivery. For this purpose, I need your phone
number with your telephone country code. So I'd appreciate it if you
would send me your telephone number after ordering, it will shorten the
shipping time.
