It depends on where you are. Order processing time takes 1-3 business days.
If you are in the United States or Canada, we give priority to delivery at the local warehouse, which will take about 3-5 days. If the products are not available at local warehouse, then we will ship at the Chinese warehouse, which will take 8-15 days.
Delivery to other countries will take 8-15 days.
At this time we only ship to the US. We recently built a warehouse in Canada, and it only takes 3-5 days for all cars and planes to be delivered to the local area. We will continue to build our own warehouses around the world, including Europe, Asia, etc., so stay tuned...
We only ship these two sizes to the US and Canada because they are too bulky to ship from our warehouse in China.
