General Guide about shipping

Combine shipping with other items to reduce shipping cost are welcome, 

and please waiting my new invoice, do not direct paying by eBay auto-checkout, 

Because it is usually incorrect.

 Will ship worldwide by post " International Airmail ePacket " without insurance, 

The delivery is usually 2~4 weeks, but no warranty about delay, depends on the post / Customs.

If you need the fastest delivery, take EMS please, but more expensive.

If you need insurance, email me before paying, please.

If items total price is over US$60, please consider to do insurance for them.

About multiple items order

1.   Please write the items No. and order quantity to me by eBay message, then, I will create a new item that combines all items and one package shipping for them and single shipping price to you.

2.   Or, directing paying money by eBay check out processing, and I will auto do “too much shipping price refund” to you by eBay after shipping.
