Hotel Amenity Set - 300 yen with Yu-Packet Post Mini!

New and unused, but kept at home.
Will be sent in a 60-size package.
Since I won't be using them, they would just become trash.
I can include cotton swabs or cotton balls in the gaps for those who wish.
How about these for those who travel often or use them at the gym?
If they fit in a Yu-Packet Post Mini, I will sell them for 300 yen, so please comment.
