We started selling THE SONIC SEAL in 2008. It's been ten years and over 100,000 seals sold.
Nothing can leak through the seal. It keeps it dry and clean.
This is the only place on the planet to buy these seals. We charge $2.50 for shipping, the exact cost of the USPS stamp.
We have been selling The Sonic Seal for nine years and tens of thousands of you have sealed your brush. Thank you!!!
