About Us

Beauty should fit into real life.

At Sinokame, we started with a simple thought: doing your nails shouldn’t feel like another task on your to-do list.

Traditional gel manicures can be messy, time-consuming, and full of extra steps — base coat, color, top coat, multiple bottles, brushes, and cleanup. And going to the salon isn’t always convenient when life is already busy.

So we created OneGel Pen to make gel color feel easier.

A pen you can hold naturally. A brush you can control. A one-step gel formula that doesn’t need a separate base or top coat. Just twist, apply, cure, and get on with your day.

We designed it for real routines — quick manicures before the weekend, touch-ups before dinner, packing light for a trip, or simply having a little time to yourself at home.

Because beauty doesn’t have to take hours to feel good.

At Sinokame, we’re here to make nail care simpler, more approachable, and easier to enjoy — one small step at a time.

Less mess. Fewer steps. More time for you.
