packets of ketchup are super wasteful

Noone wants to hear this one because... we are spoiled and the alternative fucking sucks...

Diapers and wet wipes. Most are not biodegradeable. That one is the one I am guilty of that bothers me the most.

Individually wrapped slices of cheese have always seemed pretty egregious to me

One of those coffee pods.

Packets of mustard

This one’s done to death, but kCups.

Also, plastic water bottles.

A more novel pick would be those plastic ez floss picks.

The tiny, plastic, fish-shaped soy sauce bottles you get with takeaway sushi.

Not as bad as the others, but it's been on my mind... My wife bought a box of Ding-Dongs (my daughter begged her) and inside, each one was individually wrapped. They could have put them all in one tray.

All those individually wrapped candies EDIT: MicroSD cards!!!

Anything sold single dose.

Carton of toothpastes

taco sauce packets at taco john's are a lot worse in the 'waste per packet per quantity of sauce' category.

Condoms

(people here really don't understand jokes)

Packets of tears.

Wrapping straws.
