Since I'm usually busy with work or at least jotting stuff down in my diary. A comfortable and easy to use pen is ideal. But you don't always have to use boring ole' pens. Get a cute kawaii pen! As you write, the sushi floats up and down inside the pen. Seriously, i want one of these. There are many other kinds but i thought this to be the nicest.
How much: $5
Where to buy: GAMA-GO
