Six In The Set
Six is a useful number. It fills one basket generously, splits between two children without an argument, or covers a table of classmates when each one takes a single bracelet. Every design differs from the next, so a child who wears one and trades another still ends up with something they did not have before. Nothing in the set repeats exactly, which is the point of a mixed pack.
Elastic Cord Only
The cord stretches, so a five year old and a teenager can both get one on without help and without a small metal clasp that ends up on the floor. They weigh almost nothing on the wrist, which is why they stay on through an egg hunt, a lunch and a car ride home rather than coming off at the first inconvenience and disappearing into a coat pocket.
Egg Hunt Prizes
Wearable favors do better than sweets at an event where the children are already full. These work as prizes at a hunt, small rewards in a classroom, giveaways at a spring carnival or handouts at a church gathering. A teacher or an organizer can hand them out one at a time over a morning, and each child walks out with something visible on their arm.
Tucked In A Basket
Small enough to sit under the grass at the bottom of a basket, they fill space that would otherwise go to more candy. The same applies to goodie bags and pinatas, where something flat and light travels better than a boxed toy. Parents buying for several children at once tend to spread one set across a few baskets instead of stacking them all in one.
