This is a set of 5. If you need 6 or more, please contact me, and I will add them at 40 yen per button. These are buttons for rugby jerseys. They are made of materials and specifications that prevent injury in the intense sport of rugby. The diameter of the button is approximately 14mm. They are harder than Canterbury rubber buttons. (Please refer to the third photo for the size) These buttons are made of TPE material, which is resistant to cracking even when impacted. They are ideal for sportswear such as rugby shirts. #RubberButtons #TPEButtons #SiliconeButtons #RugbyJersey #RugbyShirt #Buttons #RubberButtons #SiliconeButtons
