The most popular size in the Hama range is the Hama midi beads with a diameter of 5 mm. We recommend midi beads for children aged 5 and up, as their motor skills are sufficiently developed at this age. Children and adults of all ages can have a lot of fun with these plastic beads, whether they are ironing or stringing them. The beads are made from PE and are safe for children in case they are accidentally swallowed. The Princess ironing beads blister pack includes approximately 1,100 beads, as well as a suitable pegboard, instructions, and ironing paper.
