The bottom remains unglazed, in normal use this is not visible and even provides some grip.
Suitable for short (half length) candles with a diameter of about 22mm.
With a full length candle it is likely to topple over and might not visually match.
Please handle with care and do not to let the flame get to low/close to the stand.
I recommend to add a little wax between the candle and the stand so it sits tightly,
and/or wrap the bottom of candle with aluminium foil.
