Sounds like it must be balsa. Balsa comes in variety of densities--maybe
this is some of the heavier stuff. The really light stuff you could never
do this with. If it were spruce if would feel more like a typical softwood,
like pine.

That's foam-core board. I don't think that would work, either. Sentra is
available from sign shops and plastics suppliers, like acrylic. You can't
really tell that it's expanded (doesn't look foamy), except that it lighter
and more flexible than acrylic.
If you can get balsa to do this Sentra would probably work great.

I didn't realize you wanted it to stand out. They make it in white, beige,
red, green, etc.
