Merkpol rubber balls, 30 mm diameter, pack of 50 pieces. These solid elastomer balls are designed for general-purpose use in hobby and craft projects, educational activities and as replacement parts for small devices. The 30 mm size offers a compact, easy-to-handle form factor while the elastic material provides bounce, resilience and resistance to repeated compression.
Advantages
The set contains 50 identical rubber balls, providing an economical supply for classrooms, workshops or bulk projects. Made from a durable elastomer, each ball retains elasticity over repeated use and resists permanent deformation under normal conditions. The uniform 30 mm diameter ensures consistent behaviour in mechanical assemblies, teaching demonstrations and model making. The smooth surface simplifies cleaning and handling.
Suitable for
- Educational demonstrations and classroom activities
- Hobby and craft projects including model building
- Replacement parts in small devices and mechanisms
- DIY prototypes, experiments and physical demonstrations of elasticity
- Bulk replenishment for workshops and craft groups
Key specifications

How to use
Use these rubber balls straight from the pack for classroom exercises, craft assembly or as spare parts. For mechanical or replacement applications, select the ball and verify fit within the housing or mechanism to ensure correct clearance and movement. Clean with mild soap and water if necessary and allow to dry before use. Avoid exposure to strong solvents or prolonged high temperatures that could affect material properties.
Usage recommendations
Store the balls in a cool, dry place away from direct sunlight and ozone sources to prolong elasticity. When using as replacement parts, test one ball first under expected load conditions to confirm durability and performance before substituting the full set. For classroom use, supervise small children to prevent accidental swallowing.
