What's Inside the LEGO Builder Box?

20 sealed LEGO sets - from the largest ship LEGO has ever produced down to polybags from Marvel, Minecraft, and Star Wars.

The chase item is the LEGO Titanic - 9,090 pieces, over four feet long, and one of the most expensive sets LEGO has released. Behind it: Hogwarts Castle, the Architecture Taj Mahal, and a Hogwarts Castle Hospital Wing expansion. Four display-grade builds that collectors plan shelf space around.

The mid-tier mixes motorsport with licensed themes: a Bugatti Chiron Pur Sport, a Lamborghini Revuelto & Huracán STO, Harry Potter Dobby, BrickHeadz Obi-Wan & Darth Vader, an Oracle Red Bull Racing RB20 F1 car, BrickHeadz Mandalorian, Speed Champions McLaren F1, and Speed Champions Aston Martin. Hedwig and a Minecraft Dripstone Cavern round out the middle.

The floor features a Creator Retro Camera, Classic Creative Suitcase, Marvel Iron Man Polybag, two Minecraft polybags, a Marvel Spider-Man Polybag, and a Captain Rex Y-Wing Microfighter. Smaller builds, but every one is a genuine sealed LEGO set from a named theme.

All 20 sets and their exact drop rates are listed before you open.

How the LEGO Builder Box Works

The full drop table is above - 20 sets, all visible with odds. Open the box and the set is yours. Ship it sealed in original LEGO packaging, ready to build or display. Pull a Minecraft polybag but had your eye on the Red Bull RB20? Trade it in for credits and try again, or spend them on Pokemon cards, tech, anime figures, or any other category on Cravin.

Where Builder Sits in the LEGO Lineup

Cravin has three LEGO boxes. Essentials at /lego-mystery-box is the entry point - 19 smaller sets, polybags, and mid-range kits across seven themes. Ultimate at /lego-ultimate-mystery-box is the premium tier - Death Star, McLaren P1, and flagship collector sets.

Builder is the middle ground. The Titanic and Hogwarts Castle give it a ceiling that rivals Ultimate, but the floor includes polybags and microfighters that keep the box accessible. The motorsport lineup - Bugatti, Lamborghini, Red Bull RB20, McLaren F1, Aston Martin - is the deepest of any LEGO box on Cravin. If you're building a Speed Champions or racing collection, this is the table to play.

I pulled a polybag but wanted the Hogwarts Castle. What now?
