Ink Review - Pilot Iroshizuku tsuki-yo

Hello, Chrissy here again and today I’m reviewing Pilot Iroshizuku tsuki-yo ink.

From Japanese this translates to moonlight and it is a very nice mid to dark blue/ slightly blue-black colour. It’s a very attractive shade and a lovely ink to write with.

Tsuki yo didn’t suffer from any hard starts or non-starts when I put the uncapped pen down to do swab tests, dry times and water resistance. It felt quite wet while writing.

It dried quite quickly in just over 10 seconds on the Clairefontaine Triomphe paper and didn’t smear after it was dry.

Available in attractive Pilot Iroshizuku 50ml glass bottles from The Writing Desk
