In keeping with the ancient Sanskrit advisory to simplify my life, I chucked my combs yesterday.
I had two: a pink one with a handle and a faux tortoise shell with fine/coarse teeth.
eBay never entered my mind, but perhaps I should have put them in storage, until Junker House is opened to the public and they could be laid on top of the bathroom vanity, along with my tube of Crest and vial of Ban.
