just realized most people have no idea how big is .4 inches lol. like when you see that measurement online you think it's way bigger than it actually is. it's basically the width of your palm or a credit card plus a tiny bit more. 10.16cm if you're metric. honestly the easiest way to picture it is just lay down your fingers side by side, that's roughly it. way shorter than a dollar bill btw. i always see people confused about this when shopping for stuff online. 4 inches is that awkward middle ground - not tiny but definitely not long either. kinda wild how abstract numbers feel until you compare them to something real
