I bought two, both different size fittings, both black. First turned up grey then a week later the second turned up black with a bag of skittles lol. Can't complain cheap and do the job, also handy for the small engine bay. Have noticed oil in one but not enough to drain due to the design, the other is clear. Happy with the product and since im not a show car guy not bothered about the different colours, also reminds me which cam cover the come from
