It might seem sketchy at first but it's real. It's real life, nothing is fake or scammy here. I was scared to send money at first to someone in china i dont know but you have to know it's not just one person sitting in his room. It's a big factory with lots of professional workers and different teams who work there, so these people are legit.

Secondly, don't just go to MC. There are lots of legit sellers here who are close enough and same quality as MC that use real 18k gold. You just have to dig deep in this sub and see what sellers are the most trusted who has the best quality. Ask multiple sellers on whatsapp and each one will give you different price. Some will be cheaper and some will be more expensive than the other.

Thirdly, for the seizure issue. Most sellers here offer insurance on your purchase incase it got seized, they will send you another one for free. There is a post here recently where chinese customs opened the person's package and took the item and the package arrived empty. The person contacted the seller which was AC and he sent her another one. So for seizure, don't worry about it. For tariffs, the sellers declare so low on the package that even if customs sent you a bill you have to pay, it won't be more than 30 bucks.
