Day & Night Marks

Day & Night Marks absorb light energy during the day and produce light at night so that items such as slippers, spectacles, and water glasses can be found during the night.

Day & Night Marks are a series of products designed for people to use when they wake up during the night. It includes slippers, spectacles, and rubber bands (which could be placed on any number of objects such as drinking glasses, water bottles, or telephone handsets). Day & Night Marks use luminous materials to absorb light during the day and produce light at night. People can take advantage of the light to find items at night without bothering others.
