Stainless Whistle Red Yellow Card Kit

A purpose-built referee kit comprising two rigid plastic signal cards (red and yellow, 11 x 7 cm), a slim-fold wallet (8.3 x 12 cm) engineered for repeated opening and card retention, a high-fidelity stainless steel whistle (4 x 1.5 cm), an adjustable nylon lanyard, a standard graphite pencil, and a compact lined notebook with football-specific score templates. Every element is sized and selected for practicality: the wallet closes flat for pocket storage, the whistle produces a sharp, non-fatiguing tone, and the combined weight remains at just 20 g — ideal for on-field agility and daily carry.
