pill container

A friend has asked me to buy her a silicone pill dispenser called "PECON" when I go to Japan.

Can anyone tell me if these are available at drugstores or any other place (apart from the designer in Asakusabashi)?
They may hae been around a few years ago.

thankyou!

This seems to be a designer stuff, so you might not find it at just any drugstore - there is one stockist MoMa store in Omotesando in Tokyo:

I have the name of a shop in Omotesando, Harajuku which sells these containers. Idea Seven Sense. Can anyone gie me directions from JR Harajuku station to this shop? I know the exact location KiddyLand & Oriental Bazzar as landmarks also.
