The calculator is fake they will add 3 times or more the charge and call it dimensional weight - that is if they decide to ship to you at all! Don't fall in their trap! At least they was my experience.

I think you may be okay with makeup however, i don't think you will like the service or the cost. I always got my packages but, a lot of times i regretted using them because two weeks of back and forth emails, they take a day or two to respond if you are merging two or more orders. And it seems to me the first order was reasonable but after that the prices were pretty high.

I lost 500 $. Never are sending. For them it was dangerous goods (silicone patches for medical use)

Please be very careful, they are a fraudulent company as I lost $499 to them.
