Looking For Ideas On Non-car Part Sales

[YourConfused]

I have a piece of personal protection that I am wanting to sell. I am seeing these sold online for twice what I paid for it and would like to sell mine, but don't know where to sell it. I am not saying what it is because I am sure this not the place for that, but I will say that that it has a clip. Ebay and craigslist don't allow selling things of this sort and I was just wondering if anyone here would know where I could post such an item online for sale. It is almost new, and I need some money to feed my SVX habit. It's 100% legal and 100% fun, but not a take-it-to-work-with-you kind of fun the SVX is.
