Cheap plastic product, sent separately in an envelope, unmarked and unwrapped. I used this with our portable RV because I thought it would be a faster and better option than what we have done in the past and let me tell you I spent so much time getting this to help me align our RV that I thought I might be doing wrong. Every time I adjusted the jacks or moved the pads, I could step back and visually see that the RV was NOT level. I finally decided to test the accuracy of this level with my square level and in doing so I discovered that it's not me using it incorrectly or the ground we're on, it's the level itself that's disabled and inaccurate. Needless to say I'm a bit frustrated and now we're on vacation and I need to use 2 of my bar levels as before or just do it a little by eye.
