Neutrons are made of on up quarks and two down quark (and a lot of gluons).

Antineutrons are made of on up antiquarks and two down antiquark (and a lot of gluons).

There are no (anti)protons or (anti)electrons inside (anti)neutrons.

Nitpicking: attraction -> charge

> If an antimatter plastic comb attracts antimatter styrofoam crumbs, those crumbs will be repelled by the matter plastic comb (luckily for them).

IIRC the charge in the comb induces a charge in the crumbs. If the charge of the comb is X, the -X charges move closer to the comb, and the X charges move far away. And that those displaced charges create a dipole that is attracted to the comb.

So I think the anti-comb would attract the normal-crumbs and create a huge explossion.
