Sarawak

Hello all, my name is John and I found this sight thinking it would be the best place to get an expert opinion. I have come across what I believe is a Sarawak Malaysian hand carved tatoo box (bungan). I cannot find any similar exact photos of this on the internet. Looking at similar carving work it looks like it may have been something a Olang Ulu woman may have owned. This little bit of info I got off a small printed tag that was on the piece like it came from sort of museum. Hoping someone can help me.
