/cgl/ - Cosplay & EGL

I need one last piece to my Kintaro Oe costume, and that is the backpack. As expected, this has been the hardest thing to find remotely close to the one in the show.

First of all, most backpacks don't have that flap and clips on them anymore (that was a 90's thing). I found one on amazon that is red (see picture) but there is no black on it, and it has leather straps. I've search all over amazon and other online stores but can't find anything closer than this.

Does anyone know of any backpacks that would fit better than the one pictured? I am planning on checking my local thrift shops for an older-style backpack but nothing is guaranteed with those places.
