"To Whom It May Concern December 2023
I first came into contact with Mr Andy Ye of Hwashow Industry Co Ltd in 2014 when I was exploring a prototype for our product.
Mr Ye (Andy) bent over backwards to help me produce our first product and as our business has grown and our product range has grown here in Australia, in the USA and Canada, Andy has been with us every step of the way with outstanding service and support.
Andy also sources many additional items as well as looking after their manufacturing to a high standard and also understands our stringent demands when it comes to quality.
Andy's wife Alice looks after the shipping and paperwork in the most efficient way you can imagine. Every shipment sent is very well priced but more than that, their administration and paperwork is exemplary. We always received excellent photos of our items in boxes and cartons within the crates. Our products arrive safe in excellent condition with the best packing into crates we have ever experienced. Outstanding.
I completely trust and recommend Hwashow, Mr. Andy Ye and Alice of Hwashow Industry.
We are happy to talk directly with anyone if they would like more information.
We wish Hwashow great success in gaining (our) future global customers."
