In Iran there are not so much trusted places to buy hardware wallets.

This is because of combination of several facts:

1) cryptocurrencies are still not recognized official by the government. So most of the transactions are happening underground.

2) Secondly the fact that sanctions are in place against Iran. And therefore, it is not possible to buy these products directly from the manufacturers.

3) Limited number of companies are shipping wallets to Iran. Therefore it is not possible to receive the wallets directly in Iran   

4) Banks in Iran are not connected to the outside world ! and therefore you can not pay for your purchase!! lucky us that hopefully we can pay using ,cryptocurrencies to some of these companies. But due to other reasons still you can not get your device in Iran directly.

I found a website that sells hardware wallets in Iran
کیف پول سخت افزاری https://ledgernano.net/

It is possible to buy ledger Nano from this company -they claim they indirectly represents ledger in Iran. They have got range of products from ledger including Ledger Nano Xhttps://ledgernano.net/product/ledger-nano-x/, Ledger Nano S https://ledgernano.net/product/ledger-nano-s/, and even soon Ledger Nano S Plus https://ledgernano.net/product/ledger-nano-s-plus/.

These products in Farsi are called:
کیف پول لجر نانو اس پلاس https://ledgernano.net/product/ledger-nano-s-plus/
کیف پول لجر نانو اس https://ledgernano.net/product/ledger-nano-s/
and لجر نانو ایکس https://ledgernano.net/product/ledger-nano-x/

Leger is easy to trust because you can check it with 
I am personally mostly interested in Safepal S1 , and Cool wallet.
They also offer safepal https://ledgernano.net/product/safepal-s/

Is there any advise how can I trust that I buy a genuine wallet from them? I contacted safepal both on twitter and their website they are not really clear about it.
