If you're not too tired of hearing me talk about candles (!!) then have a look at my new Old Dripping Candles range in 1:24 (half inch scale).
For those that are unsure, 1:24 scale / half inch scale means that half an inch = a foot in real life.
My tallest candle is 1.3 cm and smallest is 0.5 cm in height.
Perfect for your 1:24 scale Harry Potter dollhouse miniature scene!
