Holds up very well - I've read other reviews of people saying they fall off but they don't. Use common sense and clean the stain with acetone or brake parts cleaner and you'll be safe without tape. I even stacked them on top of each other and had no problem getting them out. The paint is really black and looks good. 1/8 ounce is half the size of the standard weights that stores use, so using twice as many weights with these smaller denominations can be annoying and not as aesthetically pleasing. If you're really prone to OCD in terms of balance, use these - otherwise I recommend getting the same product in the 1/4 oz size. There is enough weight in the box to probably craft 10 tires.
