Hi Scott,
My critiques tend to be long, so please let me know if anything is unclear.
1. Photographs- Shadows are not your friend. Scott, the photos are what's keeping your items from selling. Your shadows are killing you. I suggest waiting for a sunny day, near a window and with every light you own surrounding the item. Honestly, I look like a whackadoo when I take pictures because I remove the lampshades and usually have lamps surrounding the livingroom mantle where I take photos. If you can remove as many shadows as possible you'll look far more professional.
2. Review your listings for grammatical errors. There are a lot of incomplete sentences or run ons. I HATE being the grammar nerd of Etsy, but if you don't spot errors on big brand name retailers we need to at least hold ourselves to that level of constant editing and such.
3. 30 Second sales pitch. Read all of your listings (or take 4 one row at a time) and read your listing aloud and time yourself. Can you make an effective sales ad and make it sound good OUT LOUD? Your average shopper spends LESS than 30 seconds on any single page (this includes the time they take to look at your photos inside a listing) in your shop. Get your listings to be catchy and short enough to get out the important info. You can, of course, add info about customs at the very end. Remember to make the listing count.
4. Store policies. You have almost no information (besides the bare minimum) in your policies. Most people won't both purchasing from a store without a policy section that states the general guidelines for shopping with you. There are a lot of questions that you haven't answered yet in your policies.
5. About section. This is where you have the ability to tell people what your "brand" is. Answer the "Who, what, when, where, how and why" of your shop. Why should I buy a Japanese box from you over someone else who sells something similar? People love shopping on Etsy because they like supporting talented artisans. Make sure you take the time to introduce yourself. :) Endear yourself to your shopper.
6. Your shop banner doesn't match the quality of your items. While the banner does match the type of items, the quality is lacking. Look at how beautiful your shop is, then look at your banner. What small changes would make the banner more cohesive with what you're selling? Trust me, your banner doesn't do any justice for your wonderful items.
I hope this gives you a good outline of things I would do, but remember that your shop is YOURS. Only do the things that feel right for you and your shop. :)
Good luck!
