Yes. We provide free shipping to over 200 countries around the world. However, there are some locations we are unable to ship to. If you happen to be located in one of those countries we will contact you.

What about customs?

We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

Do you provide tracking information?

Yes, you will receive an email once your order ships that contains your tracking information. If you haven’t received tracking info within 5 days, please contact us.

My tracking says “no information available at the moment”.

For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.

Will my items be sent in one package?

For logistical reasons, items in the same purchase will sometimes be sent in separate packages, even if you've specified combined shipping.

If you have any other questions, please contact us and we will do our best to help you out.

Ojo, funciona de lujo, pero no olvidar que son prismáticos, es decir, no son unas gafas de visión nocturna, esto sirve a partir de 10,20 metros adelante hasta 400 metros o más. Viene con cinta para colgarlos del cuello, incluso los puedes montar en un trípode.

The package arrived after three months, about two months he shot himself in customs and after paying them they don't tell me anything, I arrive in perfect condition and the communication with the store was perfect every moment I asked for information I answer and help me in everything, thank you for all seller, I recommend this store and the seller but the Spanish delivery system leaves much to be desired, but Post Office is a mess and the Spanish tax mafia
