The last stop of the day was a craft store named Kinkado. www.kinkadou.com
It's not far from Ikebukuro station.
They sold all manner of craft items, such as: fabric, craft kits, beads and yarn.
I purchased many packets of beads, as well as some lovely chirimen fabric . In the basement there was a Can-Do 100 yen store, and the ground floor sold cosmetics. Credit cards are accepted.
