The LEGO Doctor Who 21304 set offers a smaller minifigure pack but unique time-travelling elements. The build includes four minifigures: two Doctors (sw185 and sw186), a companion (sw187), and a Dalek (sw188).

The build is relatively simple, with most pieces fitting together easily. It features a TARDIS model that can be attached to the main body, providing a unique display option for fans of the show.

While not as complex as the Fender Stratocaster 21329, the Doctor Who 21304 set is a fun build with a strong connection to the TV series and its iconic characters.

How does the build experience compare?

The Fender Stratocaster 21329 requires a single-sitting build due to its complexity, while the Doctor Who 21304 can be completed over multiple sessions. The Fender Stratocaster has intricate printing on the body and headstock, making it a more challenging build with several sub-assemblies.

The Doctor Who 21304 is simpler in terms of build technique, with most pieces fitting together easily. However, the TARDIS model adds an extra layer of complexity for those who want to include it.

At the halfway point, a builder working on the Fender Stratocaster will feel more accomplished due to its intricate design, while a Doctor Who enthusiast will enjoy the unique elements like the TARDIS and time-travelling minifigures.

How do they display together?

The Fender Stratocaster 21329 requires a dedicated display plinth that comes with the set. It reads best in profile, with the guitar standing upright on the plinth. The Doctor Who 21304 fits on a normal shelf and can be displayed alongside other sets or minifigures.

Lighting is not as critical for the Fender Stratocaster, but it benefits from good lighting to showcase its intricate printing. The Doctor Who 21304 requires less lighting due to its simpler design, making it a versatile addition to any shelf.

Why does sealed matter for these sets?

Sealed copies of both sets are crucial, as used versions may lack printed parts or minifigures. The Fender Stratocaster 21329 is particularly sensitive to wear on the body and headstock, while the Doctor Who 21304 might lose its TARDIS model if not sealed properly.

For these reasons, buying from BuyMyBricks ensures you receive a complete set with all elements intact. The Fender Stratocaster requires careful handling during assembly to maintain its intricate printing, and the Doctor Who 21304 benefits from being sealed to preserve the TARDIS model’s integrity.

A sealed copy is essential for both sets to fully enjoy their intended build experience and display potential.

How BuyMyBricks verifies sealed retired LEGO

Every sealed retired LEGO copy on the BuyMyBricks shelf has been through a five-point inspection at our Yorkshire warehouse before it gets listed for sale. The same inspection runs on every retired set we hold, regardless of theme or price band, because the failure modes for retired LEGO are mostly theme-agnostic.

What we check on every box, in order: (1) Original factory seal stickers on every flap, intact, with no peel-and-restick edges. (2) Tape integrity across the top and bottom seams, with no replacement adhesive. (3) Set-number match against the box artwork and the LEGO part number printed on the back. (4) Box-condition pass for crushing, tears, water damage, or storage warping that would compromise a display copy. (5) Photographic record of every face of the box, kept on file against the listing.

If a box fails any of those five checks on arrival, it does not get listed. If a sealed set reaches you in a state that does not match our description, we refund in full. That is what makes us a specialist rather than a marketplace.

The retired LEGO authentication checklist

Whether you buy from BuyMyBricks or compare elsewhere, these are the seven checks that separate a verified sealed copy from a damaged or fake one. Every retired LEGO listing on the BuyMyBricks shelf has passed all seven before it goes live. If you are buying on the open market instead, run the list yourself before you part with money:

• Original factory seal stickers on every box flap, intact and not lifting at the corners.
• Tape integrity across all seams — original LEGO tape only, no replacement adhesive.
• Set-number match between the printed front of the box and the LEGO part number on the back.
• Box edges and corners free of crushing, denting, water damage, or storage warping.
• No re-shrinkwrapping — resealed copies often have looser, foggier shrinkwrap than factory-sealed copies.
• Country-correct artwork matching the LEGO part-number suffix (EU vs NA vs UK box variants).
• Photographic provenance — clear, well-lit photos of every face of the box from the seller.

Storing and displaying retired LEGO sets

A sealed retired LEGO box is a long-term object. Three storage rules keep a sealed copy in the same state it left our warehouse, whether you plan to display it sealed, build it years later, or hold it as part of a curated collection.

Keep boxes flat or upright, never stacked under heavy weight. Stack pressure crushes corners over time, especially on lighter cardboard from older System and Speed Champions lines. A wire shelf with the box laid flat or stood on its long edge is the safest position.

Stable temperature and low humidity. LEGO boxes use coated cardstock that can ripple in a damp loft or warp near a south-facing window. A bookshelf in a heated room at normal indoor humidity is fine. A garage, an unheated outbuilding, or direct sunlight is not.

Plastic UV-shielding sleeves are optional but help. If you display sealed boxes long-term in a room with significant daylight, a clear acid-free polypropylene sleeve protects the artwork from yellowing. Specialist LEGO box-protector sleeves are available in standard sizes that match most retired releases.

If you plan to build the set rather than hold it sealed, the only thing to watch for is sticker-sheet drying-out: stickers from the early 2010s can lose adhesion in very dry storage. Build within five to seven years of release if you intend to apply the original stickers.
