Fun stuff and a quick lunch at Tokyu Hands Department Store in Shibuya, Tokyo, Japan! And possibly the best mechanical pencil ever!
Tokyu Hands is a department store in Japan that has sections of floors dedicated to various things you might need. I swear that half a floor was filled with pens, pencils, and other writing implements. Another half of a floor was dedicated to paper and paper goods. They also have DIY, kitchen, model planes and vehicles, and several other categories. According to their website, sushi goods, health related goods, train related goods, hot/cold insulated boxes for food, and grooming goods are the top 5 most popular among customers. But they do seem to have a bit of everything!
Update: They also have 2 locations in Singapore now.
