Kleenex, tissue. Band aid, bandage. Xerox, copy. IPad, tablet (some people call their android tablets iPads) Plucker, flosser.

It's not really that bad. Some are even shorter:

Google, search. Invisalign, retainer.

Some are iffy:

Sharpie, permanent marker. (You could just say marker, depending on if you have any other markers in the house to disambiguate from.)

And some are definitely shorter as brand names:

Q-tip, cotton swab Velcro, hook and loop Sawzall, reciprocating saw

(And if there was a shorter name for "oscillating multi tool" I would be so happy.)

I can't think of any others.
