eBay glove seller "junkonsale" sold these Ines black leather opera gloves for their Buy It Now price of $293.99. These gloves were a size medium, silk-lined, and measured an impressive 26" long. The almost $300 selling price is especially impressive considering these were pre-owned. The seller stated that these were more than $400 on the Ines website.
While these are very nice gloves, I'm not sure why the maker of such a high-end pair of gloves had to use a horizontal seam (see second photo) near the wrist. It's like these were originally a wrist-length pair of gloves and the manufacturer decided to make them opera length after the fact. For me, this horizontal seam on long gloves can often be a deal-breaker, especially on expensive gloves.
