Pegs!!

I just had to buy these whilst out shopping, though I am afraid that the advertisers will think I have fallen for their jargon!
These clothes pegs were sold as "eco pegs". The reason? Because if you hang your washing outside on the washing line you save lots of energy that you would've used from putting your tumble drier on.
And also they were even better for the environment because they were made from post and pre-recycled plastic. Now I am sure post recycled plastic is plastic that hasn't been used for anything else yet so not able to be recycled. So these pegs weren't even from 100% recycled plastic though the wording could've confused someone, and probably did.
Or has everyone bought them because the wording is just so amusing?
