A great place to check out old Korean; toys, magazines, stickers, phones, postbox, candy... But it's not limited to only Korean things. It also has items of Spider man and Darth Vader.
It's a great place to get lost in for a little while. The space is not very big. But I had to make multiple rounds because there was always something I had missed before. Toto's Old Things is located on the second floor and its name is written in Korean('토토의 오래된 물건'). If you like old, dusty things with a story to tell you should definitely consider a visit.
