Mother-in-law's Tongues, 28cm, in a pack of 6 units, reference 53100, are rollable party whistles that unroll when blown. This is the classic party toy associated with birthdays and celebrations, which makes a characteristic sound when blown. With only 6 units, this pack is more suitable for small or family parties, unlike the 100-unit pack of the same basic reference. It is a preferred option for those who only need a few units for a smaller celebration.
