We started selling THE SONIC SEAL in 2008. It's been 12 years and over 100,000 seals sold. We are extremely grateful!
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 $3.50 for shipping, the exact cost of the USPS stamp.
We sold out again. It's crazy, but true. We're working to get more as soon as possible Thank you!!!
