School Uniform Jacket Buttons - 1 Set (5 Large, 4 Small, 5 Backings)

Buttons for middle school students' stand-up collar school uniforms.

Front large buttons: 21mm, 5 pieces
Front inner buttons: 11mm, 5 pieces
Sleeve small buttons: 14mm, 4 pieces

I believe these are unused parts,
so I will list them as like new.
I recall that when I purchased a standard stand-up collar school uniform,
buttons for both middle and high school were included.
