It was bought last year and Hakuhodo doesn't sell it at shop.
Hakuhodo recommends to use G5560 horizontally or laying down.
G5560 and G5561, both, are dense with more hair than usual.
Kazan is softer than Canadian squirrel.
If you use G5560 vertical, it could be scratchy. G5561 can be used vertically.
G5560 is recommended to be used like 'lay down.'
You can watch this after 7 mins for G5560 use.
