Found this at LOFT recently:

A massage tool.
There’s one at the office back in Nagoya, and I thought it’d be nice to have one in Tokyo too — so I bought it.
It’s just plastic, but it still costs ¥1,000.
Going to use this for a mental reset and get my work energy back.

Writing this entry officially breaks my three-day-post streak. Let’s see how long this keeps going.
