There are no export restrictions for the Twiddler. Your friend can purchase the Twiddler and have it delivered in the USA and send it to you in Russia.
We love our Russian customers but we have had to stop taking direct orders for a few reasons:
1) Credit Card fraud from Russian addresses were exceptionally high, compared to all other countries.
2) Shipping to all points in Russia is difficult using UPS, FedEx and DHL. DHL was the best courier but even then, we have had trouble getting packages delivered to customers.
So, because we have had difficulty delivering products that were paid for and getting paid for products that were delivered, we decided to stop taking orders from Russia.
Now, this is a great opportunity for a few enterprising people with import/export aspirations. We would be more than happy to work with anyone that would like to become a distributor in the region. Just stock up on some Twiddlers and we will pass on all Russian Leads and Orders to our distributors for fulfillment. If you are interested, please send an email to firstname.lastname@example.org.
