At 15% off, this is an excellent deal for this set. LEGO catalogues sets rarely see discounts this good. Retiring within 3 months, so stock is dwindling and deals can vanish fast. It has been as low as $10.49 (30% off), so the current deal is good but not the best we've seen.

About LEGO Birthday Party Cake

Unlike typical LEGO building sets, this birthday cake kit focuses on customisable celebration rather than construction play. The 219-piece set allows builders to create a decorative cake complete with flowers, swirls and up to 10 candles that can be arranged to match any age or simply used for festive display.

The buildable cake measures 7 cm high and 9 cm wide and deep, making it a compact centrepiece for birthday celebrations. Key decorative elements include colourful flowers and decorative swirls that can be positioned around the cake's surface to create different looks for each celebration.

Practical Storage Design

A hidden compartment within the cake structure provides storage space for all the decorative pieces when not in use. This feature makes the set suitable for repeated play and display, allowing the decorations to be safely stored inside the cake itself between celebrations.

The set is designed for ages 7 and up and offers flexibility in how the candles are used - either matching the birthday child's specific age or using all ten candles for maximum visual impact during party displays.
