I think you`re site is very nice. Both the pictures and product are very attractive. It looks like you`ve also had, some great media.
Are you advertising anywhere? I really think it takes time, and a lot of word of mouth. As you said you only offer one avenue for them to find you.
Good luck. I wasn`t ready to purchase today, but I did add you to my favorites!
If people like it when they see in person but not willing to buy online, WHY NOT open a retail store?
Open it at a tourist location (I think San Francisco China Town would be an idea location - good traffic, people from all around the world, and they are looking for China-related items). Once you have foot traffic and people purchase, they will show the products to their friends and families and bring in the web traffic.
It is just difficult to pursuade people to buy certain types of products without seeing and touching it in person.
