    Attention! Important information.
    Dear customer, we thank you for your interest in our products!
    Please, pay you attention to the following.
    We know that many countries have customs duties.
    Therefore, whenever we send packages to our customers, we ALWAYS use the following algorithm:
    1. We
    ALWAYS
    attach to our goods a customs declaration in which the cost of the goods/parcel
    DOES NOT EXCEED $ 20!
    Therefore, if you buy any product in our shop with a value exceeding $ 20 (or you buy several goods with a total purchase price of more than $ 20), you should know that
    WE ALWAYS REDUCE THE CUSTOMS VALUE OF THE GOODS
    and indicate the cost of the goods/parcel in the customs declaration always
    NO MORE THAN $ 20.
    2. We
    ALWAYS
    put a
    "GIFT"
    mark on our parcels in customs documents.
    3. If the real value of the goods exceeds the price of $ 20, then
    WE NEVER ATTACH AN INVOICE
    to our goods/parcels
    INDICATING THE REAL VALUE OF THE GOODS
    . We attach to our parcels customs documents in which the value of the goods is indicated as
    EQUAL TO $ 20
    .
    If any other laws apply in your country, please let us know. We will indicate in the accompanying customs documentation any value of the goods (even $ 10, if necessary), we will also indicate in the customs documentation any description of the goods that you tell us.
    4. We always
    SHIP
    our packages
    WITH TRACKER NUMBER.
    Therefore, you can track your purchase at any point along the route from our store to your home!
    5. In each of our parcels we put a small gift for our customer.
    This gift is a discount card for a trip to the Chernobyl exclusion zone. Therefore, if you want to visit the Chernobyl exclusion zone, write to us about it! We are happy to organize for you a magnificent and unforgettable tour to Chernobyl and Pripyat.
