I am using it in conjunction with other kinds and pasting it on a helmet.
I do not think that size, material and strength are problematic, but depending on people there may be dissatisfaction points.
Would it be better if you correspond to more different kinds?
Purchased for qualified display and for sticking to a helmet to give peace of mind to people around. I do not need 2 sheets, so I would like to have one larger size one more time.
