Your Child's Safety Comes First

At Kalmzo, we believe every child deserves sensory products that are not only calming and engaging but also safe to use.

That's why we work with trusted manufacturing partners and ensure our products are tested against recognised international safety standards. Every product we offer is selected with quality, durability, and safety in mind, giving parents, teachers, therapists, and caregivers greater confidence in every purchase.

EN71 European Toy Safety Tested

Our Kalmzo Sensory Worry Stones have been tested to meet the requirements of the EN71 European Toy Safety Standard.

EN71 is the recognised safety standard for toys sold throughout Europe and evaluates products for important safety requirements before they reach children.

Depending on the applicable sections, EN71 testing assesses areas such as:

  • Mechanical and physical safety

  • Flammability

  • Migration of certain elements (chemical safety)

This testing helps ensure that products meet established toy safety requirements.

Why This Matters

Choosing sensory products for children should never involve guesswork.

When you purchase from Kalmzo, you can shop with greater confidence knowing our products have undergone recognised safety testing.

Whether they're used:

  • At home

  • In classrooms

  • During therapy sessions

  • While travelling

  • As part of everyday sensory regulation

our goal is to provide sensory tools that combine quality, durability, and safety.

Our Commitment to Quality

Every Kalmzo product is selected with four priorities in mind:

✓ Safety First

✓ High-Quality Materials

✓ Thoughtful Sensory Design

✓ Reliable Everyday Performance

We continually work with our manufacturing partners to ensure our products meet the quality standards families expect.
