Have a question? We want to make sure your bag is perfect! Easy 30-day returns.

The Convertible Sea Urchin in Black Leather has a bold, almost jewelry-like quality that makes it impossible to overlook. The deep black leather makes every piece of brass stand out, while the sea urchin-inspired stud pattern gives the sides incredible texture and dimension. It is the same size as our Convertible Zip Bag, but the feeling is completely different.

Carry it when you are wearing all black and want to fully commit. Pair it with denim and a simple tee when you want the bag to be the interesting part. Take it out at night, wear it during the day, and switch the rope whenever you feel like changing things up. Somehow, it makes even the easiest outfit feel like you had a plan.

Why You'll Love the Convertible Sea Urchin

Golden Details with Coastal Soul

The contrast of rich full grain leather and warm brass gives this bag its signature personality, mixing a little edge with Wildwood’s handmade coastal charm.

One Bag, So Many Moods

Change the rope handle and suddenly your Sea Urchin has a whole new look. Matching your bag to your mood just got way more fun.

Look Closely at the Brass

Three rows of studs travel down each side in a pattern inspired by a sea urchin's beautiful spike patterns. It is the kind of detail that makes someone stop and ask where you found it.

Made with a lot of Care

Each Sea Urchin is handmade in Maine, because a bag with this much personality deserves just as much attention behind the scenes.

Frequently Asked Questions

Is the Convertible Sea Urchin really an everyday bag?

Absolutely. It may be a showstopper, but you do not need showstopper plans to carry it. Wear it with jeans for a coffee run, bring it along for weekend plans, or take it out at night when you want your bag to do a little extra work for the outfit.

What makes the Convertible Sea Urchin different from the Convertible Zip Bag?

They are the same bag size, but the Sea Urchin turns up the personality. Three rows of brass studs run down each side in a pattern inspired by a sea urchin, giving it a bolder and much more eye-catching look. If you love a bag that starts conversations, this one is going to be very hard to resist.

Is the Sea Urchin too spiky to carry?

Not at all. The studs are solid brass, but they are not long spikes, so you get all that amazing dimensional texture without feeling like you are carrying something overly sharp or dramatic (see our original Sea Urchin if you are really looking for drama!). They are there to make a statement, not turn your bag into a weapon.
