I sold my old stuff at a secondhand shop called Surugaya. It took quite long time but the result made me satisfied. I got about 37,000 yen and much more space in my house.
I had them estimated what I sell in advance. Surprisingly, they realized right although I made a mistake. I mistook one thing of similar one.
I thought my all stuff was assessed at reasonable price.
I’ll definitely ask them again next time.
