MERCO Whistle coloured 012 plastic whistle with lanyard multipack 12 pcs

The Merco Whistle coloured 012 is characterized by its unique design and unique performance. The Merco Whistle coloured 012 plastic whistle works on the principle of wave interference, which creates an intense piercing loud sound that will not die out even in the biggest crowd frenzy. The extremely powerful Merco Whistle coloured 012, made of high quality and in any way harmless plastic, is suitable for all sporting and non-sporting events, both indoors and outdoors, where an extremely loud whistle with a significantly different sound than the vast majority of whistles is required.
