Review on Valve-Loc Tire Valve Caps: 25-Pack Green Stem Covers for Cars, SUVs, Bikes, Trucks, Motorcycles - Heavy-Duty, Airtight Seal, Easy-Grip Screw-On Use by Mario Madden

What can I say, they are black, plastic, with a seal inside to prevent leakage and there are 25 of them (which I think is more than I've ever had will need, but with something so cheap that I don't think it makes sense to sell them in 4 pieces). They seem to have screwed it up pretty good, so I'll give them this. Anyway I'm happy with them and since the sellers send you a hilarious email asking you to review them I guess I should because the product is good and the email made me laugh has brought.
