I posted here for sale a week or so ago an iRig for connecting your guitar to an iOS device. When it didn't sell, I posted it on Reverb. However the listing was suspended as I didn't show the item, only the original unopened box. I couldn't sell it as new because I'm not a retailer, and they don't allow used items to not be displayed. The odd thing about that is for some things, especially anything collectable, "unopened" condition is a positive. To require opening the box potentially devalues the item. (Imagine finding an unopened in box original Arbiter Fuzz Face from 1966 and trying to sell it. Reverb wouldn't let you.) I put the exact listing on eBay and it sold within hours. They probably would argue that showing the actual item is a security issue to prevent fraud, but that's a concern with new items sold on the site too. (And the buyer has recourse if that happens.) The silly part is that I can't even delete the listing unless I correct it by posting new pictures with the item shown!
