CEO Comment

I personally experienced dropping my bag while going out with my daughter.

Through this survey, I learned that this is not just my personal issue, but a common challenge faced by many caregivers.

The Open Lock Carabiner was developed to allow easy one-handed attachment and detachment of bags, even while holding a child.

As a 'always-open carabiner' that keeps the gate open, it enables effortless bag handling with one hand.

We will continue to develop products that address real-life parenting challenges.
