Caulk isn’t something most consumers like to keep around in bulk quantities. That’s why Momentive Performance Materials’ GE Caulk Singles make sense. The 1.25oz packages of caulk are made for single use, with a tear-off top that offers easy access and internal fitments that help guide the bead of caulk. “Caulk Singles will do for caulk what the bleach pen and disposable razor did for busy people on the go,” says Rodney Hawkins, the company’s general manager. The flexible nature of the package also allows the user to push every last bit of product through the pouch. Caulk Singles retail at a suggested price of $2.29 to $2.99.
