Don’t worry.it usually takes 8-15 days by usps to arrive in your address.
The ETA date you saw on Amazon is the longest delivery date that Amazon default.
If you need faster delivery than USPS,that will be DHL(within a week),but need you pay shipping fee balance.
Or if you want get it more quickly,w suggest you change to buy blue one.
It will be dispatched by Amazon,only 1-3 days.
Any other help need,please feel free to let us know.
