I bought these completely on a whim. They were cheap, they looked quite nice, were made of cotton, and the eBay seller claimed to be a UK seller (but we know that claim to be largely complete bolllocks usually).
I wasn’t surprised when they showed up after about 2 or 3 days; I was shocked. And they fit well.
£6.43 is what I paid in total for the white pair. Also comes in blue with a fast collection of other undies to buy thereafter.
My next thong is already on its way from DeadGoodUndies.
