very soft, nice quality. easy to install. definitely measure and make sure it will fit. mine was about 12” long, and this one fits perfectly. more of a soft, washed out pink rather than the brighter pink pictured

Soft & fluffy. Stuffy arm rest.
Color: Purple, Color: Purple
Soft and fluffy & my fav color purps. Now I'm looking for other purple accessories to go with my 2021 Honda CRV. I don't think this cover would be be enough for a large SUV arm rest such as a Navigator... But yea, order if you want some color & funk in the ride
