Yes, they are a company in Poland with mostly positive reviews since they were tracked 3 years ago. They also have a social media presence with hundreds of followers and their phone number and contact information. I would say it's safe, but you can call them and speak to them to see how trustworthy they seem to you.
looks good, if it offers cash on delivery, choose cash on delivery and check the goods before the carrier.
Heres some review..
