Personalised cake toppers with a built-in sparkler holder

No. We do not sell fireworks of any kind, so the sparkler is not included and is not available as an add-on. The topper has a moulded socket built into it that holds a standard upright cake-fountain firework, usually sold as an "ice fountain". You can buy these in most supermarkets, party shops and online. Buy the sparkler separately, stand it in the holder, and you are ready.

The socket is designed for a standard upright cake-fountain firework — the short, stubby indoor kind usually sold as an "ice fountain" or "cake fountain candle". It stands in the socket on its own base; it is never spiked into the cake. It is not designed for thin handheld sparklers, which are the wrong shape, sit loose in the holder and are not meant for cakes. If the firework does not stand upright on its own base, it is not the right type.

Yes, if you use an indoor cake fountain made for the job and follow the maker's instructions. That means an upright ice fountain, stood in a holder rather than pushed into buttercream, kept clear of anything flammable, never left alone and never handed to a child. Our toppers exist because balancing a fountain in icing is the part that goes wrong. Light it, watch it, then let it burn out.

Indoor ice fountains are made to be used inside, but they are still fireworks. Read the packet, use them in a room with clear space above the cake, keep them away from decorations, hair, balloons and smoke alarms, and have an adult supervise from start to finish. Never lean over a lit fountain. We do not sell fireworks, so the manufacturer's instructions on the packet always come first.

It depends entirely on the brand and size, so check the packet before you buy — most are designed for a short burn, roughly the length of Happy Birthday. Because we neither make nor sell fireworks, we cannot promise a burn time for any particular product. Buy from a reputable retailer, read the instructions, and do a mental run-through of the moment before you light it.

Supermarkets, party shops, cake-decorating suppliers and the usual online retailers all stock them, often labelled "ice fountain candles" or "cake fountains". Buy the upright type that stands on its own base, rather than thin handheld sparklers. We do not sell them and we will not recommend a specific seller, but any reputable UK retailer selling indoor cake fountains will sell something that fits the holder.
