[ Features ]
Thermal Dots only turn black when they've reached 120°F / 49°C. If you're worried about enough heat reaching certain spots, place a Thermal Dot and know for sure. The indicator circle stays black after activation, so you can check your items even after they'e cooled down.
Fits tight spaces
Thermal Dots can be slipped between pages in a stack of books, or into the toe of a shoe.
Great for temperature verification
Not sure if the dryer setting is hot enough? Don't tumble dry your thermometer. Thermal Dots can be stuck to the drum, or placed in the sleeve or pocket of a heavy coat before tossing it in.
Individual Thermal Dots size Approx. ½" x ½"
Thermal Dots per pack: 21
