Hairspray? What does that do? And what's the difference between the two types? Suited to different types of objects? Shall I add one more question mark to my post?
I'd imagine so, but Ali Express do offer a money back guarantee type thing, although I've no idea how reliable it is.
It seems to require you to return the item if it's not as described, and I imagine the cost of posting a 3D printer back to china is not going to be insignificant.
