Shipping for repairs- best option from USA?

I have to ship my Boox back for repairs. Has anyone sent for repairs? I’ve never shipped internationally before.
Customer service said they’d refund the cost, but still have some questions.

  • Planning to ship with USPS
  • Are there any issues with lithium ion batteries?
  • Are there any customs forms to fill out?

Hello, per our customers, there will be no special issues with Lithiumion batteries or any customs forms to fill out. Please feel free about that.
