No, these are okay.
And actually, popsicle sticks will do in a pinch.
Apt username. I’m going to go with stamps.

Am I the only one here that swears by cheap, 1-ply toilet paper? One the other hand, I’ve probably gone cheap on most of the items mentioned here (excluding things like guns and airplanes that I’ve never purchased) other than tattoos.

Luckily, my sister in law found out before he’d finalized the arrangement.
