Gameboy Color Carrying Hard Case

I'm not looking to sell this, but since I posted pics of my collection years ago, I've been contacted several times through here and PMs on eBay from people asking to buy it since they can't find it anywhere else.

I did not consider it that rare, but got loads of requests, so I'm just curious.

I remember buying it new for around $10-$20 in a games store (can't remember the name) on a shopping mall in Philadelphia back in 2000.

It's not official, and has no brand whatsoever (might be Pelican though? I remember the store having lots of Pelican accessories).

I only saw one for sale on eBay, like 4 or 6 years ago at around $80-$100.
