Blokees Wheels should be collected as its own BLOKEES family rather than folded into the company’s other model-kit formats. C-series assortment releases and CT-series individual vehicles can both belong under the Wheels umbrella when officially identified that way.
Exact scale, piece count, materials, and configuration options can vary by model. Motormaster, for example, uses a roughly 1:64 vehicle presentation and includes modular trailer configurations, but those details should stay attached to that release rather than becoming promises for every Wheels kit.
The stable collecting experience is simpler: recognizable vehicles, assembly as part of the fun, compact display behavior, and a fleet-building structure that encourages multiple models to live together.
