Featured Japanese Tea Cups and Saucers

Hello again
I have recommenced unpacking my granparents boxes of goodies and found 6 of these little tea cups and saucers. I couldn't find a teapot. Using the resources I have found on the forum I have managed to identify the makers mark. The middle mark below.
The cups and saucers are very small, wafer thin and almost translucent. I'm just after a little help regarding quality and any other comments that will help me sell. Also, I have tried to find similar for sale or recently sold on ebay but I don't think I have enough info to search correctly.
As always thank you for taking the time to respond

Commonly call eggshell porcelain.

 

Yes! Thank you. That's exactly what they feel like. I am almost too afraid to handle them

 

Thank you
That's a match.

 

IIRC, these will have modest value (I haven’t checked recently, but I suspect that ceramics is still a depressed market) as they are not top quality, but a nice mass market set.

 

Thanks @i need help Very interesting.

 

Thanks so much @kentworld Any suggestions on how I should word the title when I come to sell?

 

Gosh, I haven’t sold stuff for so long, I wouldn’t know. However, if you look at the same sort of item, say, on eBay, you can see how others have titled their items for sale.

 

Thanks!! I have checked ebay and etsy. I found one listing but don't think the title is quite factual. I'll continue my search. Thanks again
