How to style hair vents on a wig?

By hair vents, I mean these pointy anime bits on a wig! I've been wanting them on my MDD for ages, but I'm scared to mess it up with products that might seep onto the vinyl or otherwise be destructive. Any tips would be super appreciated!

Ps. I'm in europe so volks wig wax is sadly not available for me

I don't know if it's available in Europe, but many cosplayers use Got2Be Wig Glue to style cosplay wigs.

Usually heat and often strong hairspray or some sort of styling gel is used ^^. Here is a video that will demonstrate it ^^. You can spray the hairspray onto a paper towel and then apply it to the sections. This hair style is usually called an “intake”.
