IT’s amusing going through this and seeing people say things like $5 is really expensive for mask. Nowadays, That’s cheap for anything other than a standard set mask. Mask set masks are usually starting at that price, and go well above it (Especially if it’s a Hau, or worse, one of the Kaukaus)
My rarest Mask is that trans Neon Green skull mask from one of the Comic Cons. I’m glad I picked it off of bricklink when I did.
Other rare ones I own are all the misprint Rurus (With doubles on the red and Blue) Three of the misprint Matatus. A gold and orange vahi. Nothing really special, otherwise.
One mask I wish I could get my hands on would be the yellow Ruru. The Ruru is my favorite ask, and yellow is my favorite colour. I’ll just have to suffice with painting one, I guess.
Also known as short shots; created when not enough plastic flows into a mould. These are supposed to be found and discarded during the quality control process, but occasionally one slips through.
@TotalMaddness I love the yellow Kaukau. I have only seen them for sale on eBay from Japan.
San Diego Comic-Con Skull Scorpio mask. Also @DuneToa I’m trying to fine Misprint mask / parts too. It’s not easy and a lot of people keep them once they find them.
