Decorate Your Shabbat Table (Y'know, If You're Rich)

I’m going to be honest and say that I have never had the problem described on the Yontifications Jewish Everyday Wine Markers website:

You’re going to love these Jewish wine markers. Beautifully designed, this set will add beauty and originality to your Jewish holiday, Shabbat or everyday table. Each marker is colorful and distinct, assuring no glass confusion for your guests. You'll never worry about setting down your Merlot and picking up Bordeaux!

See, you put these little bead-y Jew-y rings on your wine glass and then you don’t accidentally get Norman’s Manishevitz. Now, I know what you’re thinking is, “But I really wish I could get a special set for Passover,” and don’t you worry, babe. They’ve got you covered at Yontifications, what with their Passover Ten Plagues Wine Markers. Oh yes, you can have a little dead cow for cattle disease, or a tiny knife for the slaying of the first born.
You Need This: actually, probably not
Will someone explain to me who, exactly, buys this stuff?

Also, who is spending three hundred bucks on this? Seriously, who??

Oy Vey: that's really all there is to say about this
