Worry-free shopping
I love having fun colored covers for my car fresh diffuser, they fit perfectly just like the original cover did.
Really cute little colorful essential oil diffusers!
I love this for the car, the new ones are so pretty! Awesome passive diffuser.
I like being able to switch out the colors. This pack had green and pink crystals. I think it said purple in the description, but it’s definitely more pink.
These are two of my favorite colors! They give a bit of pretty 'bling' in our vehicle.
I've had one for awhile now and it's a great diffuser, now I can switch the colors out.
The Crystal Carfresh pack is wonderful and I love the colors! I am so impressed with everything I have ordered! I have another list started for an order in the near future
Just received my order, and these look even better than in pics. Colors are pretty and the quality is good.
I like there are new colors offered for the Carfresh but disappointed that the purple stated looks pink. Would have preferred a blue instead. Maybe next time.
