Review on 📏 Inch Line Diffraction Grating Sheet by Rob Allen

Even if this is the amount you need, you will find it elsewhere. Like others, I had mine wrinkled and with small puncture marks. The package was whole and undamaged but when I opened it the foil was crumpled to fit the corner. It's also hard to tell, but I don't know how accurate the description of the item is. Please just find another one here, you will regret spending money on it.
