NinjaXChange Collectible Expo in Carlsbad occupies the second floor of The Shoppes at Carlsbad on El Camino Real, operating a permanent multi-vendor marketplace for pop-culture collectibles. Established in 2023, the expo floor features rotating independent vendors selling Funko Pops, Pokemon and anime merchandise, comic books, and graded sports cards — a trading card category shared with Village-based dealer Coastal Sports Cards & Collectibles on State Street. The weekend-only format draws vendors specializing in vintage action figures, sealed wax packs, Hot Wheels collections, and convention-exclusive Funko releases not available through standard retail channels. In-store signing events have hosted comic industry figures including Jim Lee, with ticketed sessions organized through partner booths operating within the expo space. The venue's stock of franchise character merchandise — Marvel Legends, DC Multiverse, and McFarlane Toys lines — positions it within the same collector-tourism corridor near LEGOLAND California that includes the LEGOLAND California Hotel LEGO Gift Shop. Vendor booths carry PSA and Beckett-graded vintage baseball cards, CGC-slabbed comic books, and Japanese import Mafex and SH Figuarts figures priced from entry-level to four-figure collectible tiers.
