Who We Are

Yessera SitCase Inc.

Relief. Anytime, Anywhere.

At Yessera, we create solutions that blend science, comfort, and freedom—starting with our breakthrough device for TMJ relief. Born from a desire to end the cycle of jaw pain in simple, effective ways, we’re on a mission to design tools that restore ease to everyday life, so you can eat, speak, smile, and rest without tension holding you back.

Our Philosophy: Relief Without Compromise

We don’t just build products—we create solutions people can truly feel. The Era Wand Pro is a perfect example: compact, effortless to use, and powerful enough to relax overworked muscles in just minutes. Whether you’re heading to bed after a long day, recovering from stress-induced clenching, or managing ongoing TMJ discomfort, our device empowers you to take control of your relief, on your terms.

Built for Real Life

Every Yessera product is engineered around the people who use it. We listen, test, and refine with purpose, prioritizing safety, effectiveness, and simplicity. From chronic jaw pain sufferers to those dealing with occasional tension, we believe everyone deserves a better way to release pain, restore balance, and reclaim their comfort.

Thank you for choosing Yessera. We're excited to bring practical innovation into your everyday world, one seat at a time.

With purpose,
The Yessera Team
