Are these likely to hold up for years and years? Eh, not likely.  Despite the product description that these will help you to "Keep warm in autumn", they're actually really really really light and flimsy (as I expected them to be based on the images, reviews, and the other part of the description "light-weight").  They're perfect for me - I wanted them to use as hair scarves not neck ones.

I found the colors and images here an accurate representation of what I got.  There are definitely fancier scarves out there made of sturdier materials, but these look nice at a price that is budget friendly.  I do regret that I only ordered one set of them not knowing for sure that they'd work for what I wanted them for though there had been two different color sets at that time and now they are unavailable, I hope that unavailable status is temporary because for the price and compared to other options it's a pretty nice deal.
