Koyal sells wholesale products made by various companies, but as a customer service provider I do recommend them. They answer emails very quickly when you would like more detail about products, and they also have the live chat feature which gi...ves you instant customer service right at your finger tips without having to sit on hold on the telephone.
I bought the 28 inch glass Eiffel tower vases, which I thought would be perfect for my wedding. Two of them arrived broken, I quickly chatted with them online and they arranged to have two new ones shipped right out at no cost to me. However when I took them to my florist, and tried to use them with our wedding arrangements, we realized they were not made right. Some of the glasses lean slightly to the right, the taller the vases the more noticeable it is. The feet on the bottom were also not symmetrical, all 12 were not exactly the same and some didn't look very sturdy. My large flower arrangement toppled right over when someone moved the table the slightest bit, which was attributed to the asymmetrical feet and crooked stem. These vases at Hobby Lobby and other craft stores are twice as much, but none are crooked and all are very sturdy. When I talked to Koyal wholesale, they advised that its just the way they are made, that they are hand blown glass and difficult to get each one the same and perfect. I don't believe that as I can pay twice as much money for them and get good ones, so I guess this is one of those you get what you pay for products.
On the other hand I ordered their new Vintage Gold Metallic Charger plates, they were gorgeous! I did receive 150 of the wrong plates, they were the plain gold ones. I had to email them pictures of the wrong ones, but instantly chatted with someone and they paid for the shipping back and sent me the right ones within a few days.
So as far as their accessibility, customer service, and attention to providing their customers with quality assurance, I'd say Koyal Wholesale is top notch. Just beware of some of their products, as they don't personally manufacture or make the items. For the money, Koyal wholesale offers a huge savings over the traditional stores and even most other discount stores online.
