Hi Marius,
Apologies for the late reply. The suppliers we have in the directory that carry the items you're looking for are either mostly based in the US or are wholesalers. I ran a search outside of our database and found these dropshippers.
Although this supplier is not in our directory, they should be safe to deal with. We have checked their website and they do accept safe payment methods such as PayPal or credit cards. What this means is that in the event that something goes wrong with your transaction, you can get your money back.

However note that we cannot officially guarantee a safety of a supplier found outside of SaleHoo.
Hope this helps and all the best!
