The prices varied but most of them were in between 1,500 and 2,000 yen
This store is in a district called nakano. Its about 5 mins away from shinjuku. Its in a 5 store building in front of the station that sells all these kind of things. Think of it like a mini akihabara. Its really good though because I found many things you don’t see in Akihabara due to it not being as popular.
