Pack of 4 battery operated LED tea light candles.
Each candle requires one CR2032 Battery (included).
They've a "flickering flame" effect (not great but OK).
May be useful for use in pumpkins (or turnips if you're "old school"!) - particularly for younger kids as it avoids the
risk of burnt fingers. However, it might not be quite the same without the smell of burnt pumpkin / turnip ...
Although similar ones are about £5.89 on Amazon (http://www.amazon.co.uk/Operated-chirstmas-anniversary-birthday-occasion/dp/B000MFWF38)
I suspect that they're about £1 in other discount stores ...
I bought them at the new B&M store in Queensferry, North Wales (near the Lidl + B&Q), but as they were this price on the end of an aisle (rather than a 'discount stickered' item) I suspect that this will be nationwide.
Main reason for posting is to highlight the new store - as it's not even showing in the store search on the website yet (it only opened Thu 30th Sep 2010).
