A Quark brand Deep Space 9 model kit
Quark was a brand of spacecraft model kits in the late 24th century. Advertised as "authentic kits", the models had fully functional weapons, shields, and warp cores, and also included miniatures of specific crew members.
Sam Rutherford and D'Vana Tendi began building a Quark brand model of the USS Cerritos in 2380, though they never intended to finish it as they used their model building as a "social deflector dish" to keep others from bothering them. After their Cerritos model was crushed by Dooplers in 2381, Tendi obtained a new Quark kit of Deep Space 9, presumably from the Quark's Bar, for them to never finish together.

The same kit was sold at the Quark's Bar on Deep Space 9 in 2381. (LD: "Hear All, Trust Nothing")
