Replying to WTB: Cheap Skateboard Helmet-For a good cause

so i'm building a set of daft punk helmets for halloween and for thomas's helmet i'm using some really shitty cheap protec type skate helmet as a base. i don't want to pay a lot and i don't care about condition as long as it's wearable. i'm probably a medium or large. i wear a medium giro g10 if that helps at all

i can get one on ebay for like 20 bucks so looking to pay less than that. also i don't want one with too many holes, some holes are okay but i have to cover all of them in order to put fiberglass resin on so not super vented

kthx
