Timer sticky note / Sticky note

Timer sticky note

Sticky notes help people to remember what they should do in several coming days but it is difficult to remember the date of deadline of each sticky note and hard to find what to do first. The timer sticky note is designed to solve the problem. The sticky note is made by a kind of special fiber which can change it color when it is exposed in the air(the moisture and the oxygen ).As the time goes by, the color of the sticky note changes from yellow to red. The longer it exposes in the air, the redder the color. The reddest sticky note is the most urgent one you need to handle first.
