Don't bother. I ordered the 10 pack of boxes. And what I got was seven boxes. 10 box lids. And three factory defect of boxes that can't be saved they are glued backwards and attached at the sides. I worked too hard for my money to spend it on inferior product, I would give negative stars if possible

Ex Output:
negative

Put them on my 2008 jeep grand Cherokee because I put slightly oversized tires and only have had these spacers on my jeep for one month and driving home today I noticed when I got home all were loose and one broke off on driver's side front! All lug nuts were torqued properly and rechecked after the first day all brand new lug nuts! Not sure why this happened and why one is broken! Very dangerous and concerning! Now i need replacement studs.. disappointed! My wife drives this car every day with children in the car but luckily she wasn't driving it today!

Ex Output:
negative
