Our Happy Clients From 30+ Countries

I have been working with ESHINO for 3 years now, and I am so glad I chose them from the beginning. Sourcing precision parts from abroad is sometimes frustrating. I previously sourced it from factories in local, but the price was quite high. Working with ESHINO is much less hassle. Their salesman said their products were lab certified and was convinced of this. And also, they are really professional, they always know what I want, all I have to do is sit in the office and wait to receive the parts.

I get my precision ceramic components from ESHINO only at present because they are the only supplier I trust in China, my colleague has personally visited their factory and was impressed with their advanced equipments and quick feedback to clients. Even if some tiny components cost a few dollars in local, I'm willing to import them from them, not to mention that in most cases, ESHINO's ceramics are lower than the factories in Japan and Europe and with equal quality. One more thing, my consumers are not resistant to getting better guarantee for their products, so I have high expectations of the wholesaler's production capabilities, but ESHINO never disappoints me. So if possible, I suggest you try their other products as well.

The product is amazing and dealing with the supplier was easy and straightforward, prompt responses even in the weekends! They are very attentive and professional, managed to clear my doubts before making the purchase. I would strongly recommend and I'll definitely continue to work with it in future!
