Unused Gyokusendo Lettering Brushes, Set of 2 (No. 3 & No. 5), Flat Brushes Made in Tokyo for POP and Calligraphy

This is a set of two unused Gyokusendo lettering brushes.
Sizes 3 and 5.

These are from the Showa era.
They are flat brushes and can be used for creating POP displays, lettering, and coloring in calligraphy.

As they have been stored for a long time, the outer bag has some scuffs, but the brushes themselves are unused.
Would be great for those looking for a set.

Please refrain from purchasing if you are looking for perfection, as these are home-stored items.

Thank you for looking.
