PICS Posted-Help identifying a group for category listing(s)?

Pics below---I am not a collector or obviously an expert in this topic. I picked up a group of tiki mask pairs a few years ago on a whim. We have never used them and I'd like to list them on eBay but I am stumped on categories! It is a group of 10-(5 pairs). They are all different sizes and seem to be totally different styles. One pair looks Asian, others Hawaiian or African?? Any simple rules for telling the difference? Any suggestions?
Thanks in advance!
