Its NOT legal anywhere!!!!!!!!
If it says its brand X and there's no proof or sometimes just a simple receipt, its probably brand Y!!!!!!!!!!!!!!
Remember to check it out very carefully. Replicas are not okay, whereas some 'Remakes' of items are okay even though they have issues.
You will have to explain that its got all the original certificates if its a remake, always.
As if it doesn't, it will always be a copy or a scam from someone over there. Good rule of thumb. And to really sell brand name items of anything without having trouble later, you just need the receipt. A photo of the receipt from them, or having purchased it yourself you have that receipt & can use that photo.
