They fray and unravel after a few washings.
Color: Classic Color
They are exactly what I needed but after a few washings they started to fray and unravel. Also I was looking for black and had to buy the 4 different colors.

Terrible
Color: Fresh Color, Color: Fresh Color
Should be a zero! Would be shocked if these are cotton at all! Feels like polyester, unravels after one wash in a lingerie bag on handwashing—horrible!!!

Perfect size and strength for my small dog that is a heavy chewer! She hasn’t been able to destroy and chew up this one like she has with every other toy! Definitely chew resistant.
