Pack sizes range from single number sparklers (sold as one) to small sets of two larger candles, up to multicolored packs that include all 13 letters needed to spell "Happy Birthday."
Wax letter candles come with wooden sticks for inserting into cakes; number sparklers are mounted on a metal handle for holding while they burn.
Letter candles are shown as white wax pieces with vibrant colored transfer prints and are also sold in multicolored or rainbow packs that spell out "Happy Birthday," offering bold, colorful looks.
The candles are aimed at birthdays and milestone events (including milestone birthdays and anniversaries). Some sparklers also mention use for New Year's Eve celebrations.
Reviewers generally praise the design and visual impact, calling the candles cute, fun, sparkling, and vibrant. Criticisms include limited burn time or that some sparklers may take extra time to ignite; a few reviews also note that certain candles resist melting.
Sparkler number candles are ignited with a lighter and held by the metal handle. When lit, they produce a sparkling effect and burn until they go out on their own.
