Insights

A family-focused Duplo item retired as Birthday Cake (30330) has shown modest post-retirement appreciation driven by steady young-family demand, and its wide retail and gift-with-purchase distribution alongside a generic subject limits scarcity and caps upside, making it suitable for small, lower-risk holds.

Set Facts

The set includes buildable bricks to create a birthday cake for celebrations of birthdays 1, 2, and 3.

About Duplo

The LEGO DUPLO theme was introduced as far back as 1969 and is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick. Like LEGO System, DUPLO also has subthemes that are often junior versions of System themes, like Pirates and Castle and licensed themes like Disney and Super Heros.

Mix the bricks to create a buildable birthday cake to celebrate birthdays 1, 2 and 3. Easy-to-hold pieces ensure this fun toy will entertain boys and girls all year round.

For 50 years, we have been introducing DUPLO® sets to little builders with big imaginations.

Celebrate that special little one's birthday with this cute DUPLO® cake.
