Thin, but functional.
These work fine, but they are thinner than my local hardware store's version. They're also cheaper though, so you get what you pay for I guess. If you are using them inside I wouldn't worry about it at all, these work fine, but if you are using them outside in the UV/sun or freezing temperature etc. I don't know how well they will hold up. I used them outside, so we will see how well they last...
