These sets belong to the giants of the catalogue, the 1:24 kits of the Hellcat, the Typhoon, the Spitfire Mk.IX and the Fokker Dr.I. At that size an individual lap strap is about as wide as a fingernail, which changes the standard completely: Basic Line belts with visible stitching and separate metal buckles look entirely convincing, whereas an etched equivalent would read as folded tin no matter how well it was painted. Pair the set by the aircraft and the kit named in its title.
The large kits these belts are cut for are listed under 1:24 aircraft kits, where a single-engined fighter spans around 40 centimetres. If the set also carries wet transfers, they want a gloss base to sink into, which is what modelling varnishes are for. Smaller scales and the brand's complete listing are under HGW.
