Craftsmanship
The Art of "Koba-nuri" (Edge Painting) It’s not just about what we use, but how we finish it. Cheap straps have raw or folded edges. Ours are finished with Koba-nuri—multiple layers of edge paint applied and polished by hand by Japanese artisans. This meticulous detail ensures your strap looks like it came from the boutique, not a factory.

★★★★★
Matches the authentic color perfectly.
I was anxious about buying online just by looking at photos, but I was shocked—the color match is identical to the original. Unlike cheaper alternatives, you can tell every detail is crafted with care. It was worth every penny.

If you want to use it as a bag, this is mandatory.
The pouch itself is cute but hard to open and carry... until I got this strap. It's the best! Using the Bride-a-Brac as a handbag is a game-changer. I’m 153cm (5ft) tall, and the 2.5cm width fits perfectly.

Hands-free freedom for my daily walks.
Being able to go hands-free makes shopping and walking so much easier. Wearing my favorite color lifts my mood instantly! It’s the perfect upgrade for the coming season.

So good, I bought a second one for my mother.
I originally bought one for myself. When my mother saw the quality, she wanted one too! We are both extremely satisfied with how sturdy and elegant it looks.

"Thank you for visiting COTANTIN.
I didn't start this brand as a business; I started it as a mother in need.
When I bought my Bride-a-Brac, my daughter was just one year old. As much as I loved the pouch, chasing an energetic toddler without having my hands free was impossible.
I tried the 'conversion kits' available online, but they left me disappointed. The leather felt fake, the colors clashed, and the quality simply didn't match the elegance of Hermès. I refused to compromise.
So, I decided to create my own.
I spent months searching for a craftsman who could meet my exacting standards. I rejected mass-production factories and finally partnered with a master artisan who treats every stitch as art.
'With Me' is the result of that obsession. It is the strap I use every single day—at the park, on trips, and everywhere in between. It has been tested by real life, and I am proud to share it with you.
I hope you love it as much as I do."
