I have a weakness for Tsumori Chisato and the multicase card holder is too cute to pass. The classic polka dot design is given a fresh new look with gold circles. Consisting of 2 card slots, coin compartment and mesh compartment, there is a little strap you could fasten to sling it. This is very similar to Le Sport Sac E-Mook with the multicase wallet but with less compartment. Material wise, i would prefer the Le Sport Sac nylon multicase compared to Tsumori Chisato polyester patent.
Overall, i think its a good buy as its only S$17.50 for a Tsumori Chisato sling pouch. There were a dozen on the display when i was there in the late afternoon.
UPDATE : There was another shipment of about 60 at Kinokuniya Ngee Ann City.
