Hi Michelle - I think you have some great items listed and I think you are right regarding price, if people want these types of items they will pay the prices you have. 

Re your listings - I reckon to encourage a higher level of confidence by those considering purchases from you - IMO your listings may benefit from having at least a little more information - in particular, measurements / size and condition  including any flaws in your items at all, no matter how tiny. If there are no flaws, then say so.   

An example only ..... I saw a set of glasses you have listed, I thought I'll have those, but the photos gave me no indication how tall / small / large ??  I think that this particular type does come in a couple of different sizes, so even a ruler in one of the photo shots would help buyers to gauge size.

Whilst many buyers may ask questions to get this information, others like moi, may just move on if this type of information is not included in the listing.

Hope your sales improve and I hope mine do too 🙂
