Bulk Whistles 100 Pack custom orders available

100 pack bulk whistles. You know what they're for. tried and true design is back. Made them larger so they're louder. tested with decibel meter indoor and peaked at 124db but did not try blowing as hard as I can due to having dogs in my home. Please DM for custom orders, due to the larger size custom letters or numbers can be added for an additional charge.
