Selection boxes vary tremendously in terms of price, size, contents and quality.
At the lower end of the scale, the types of boxes usually pushed by supermarkets tend to be sold on a “perceived value” basis; the fact they contain a great number of fireworks appeals to the layperson who might rarely buy fireworks and knows little about the subject. Thus a box with a large amount of items in seems like great value. In truth, each of these items is likely to be very small and some of them quite underwhelming.
The box above, for example, has an RRP of £10 and contains 14 fireworks which sounds like great value. However with an overall gunpowder content of 89g, that’s an average of 6.4g per firework. To put that into context, a single £10 cake could have up to 100g of gunpowder in just the one item and a pack of sparklers typically contains around 5g.
At the higher end of the scale, specialist firework shops are more likely to sell selection boxes where the emphasis is on quality rather than quantity. Here there will be less number of items but they will be bigger and better quality.
