I see now that the fine print mentions that these do not hold taper candles, but it's very misleading to have photos of a product that isn't yours which all show taper candles and taper candle holders.
What you get is a flat acrylic disc at the top of each one.
The sleeves also appear to be much shorter than 10". I haven't measured them but I leaned a 12" candle in there to see what it looks like and the sleeve only covers about 2/3 of it, looks like much more than 2" protruding. However, the flat disc also takes up some of the space because the sleeve sits a little lower than the disc, so that could be the difference.
Overall, disappointed because I ordered these just in time for an event, and tea lights look much too short and no pillar candles are narrow enough to fit in here.
Photos #3 and 4 shown here are the only ones that show the actual product, if you look closely you can see the discs and see that there is no holder for tapered candles. This is probably why they don't show any candles inside the candelabra in this photo, because candles don't actually work in them.
