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!!!

Fun, Durable Balls for smaller heavy chewers
Color: Four colors, Size: 5cm (ball only)
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.
