I just bought these little gems from Manor House Miniatures.  I have had them before in Bentleys but these are for Chocolat.  They are hollow so can be filled and the caps actually screw off and on!  The are also the best size - totally in scale for large storage jars of all kinds.  the more you buy from Manor House the more they discount the price.  These come in pairs.  I bought six pairs so they were $1.85 a pair.  That's roughly £1.16.
