perscent / product design


Diffuser is used to remove scent, relieve tension and interior effects, but it is difficult to replace sticks and control concentration. So, ‘PERSCENT’, solved this problem. A great advantage of products is the spread of scent. We thought we needed an diffusion Tool, and we thought about how the record player would turnNING. and we also made it look like a record player. The scent instead of sound on the record player was enough to attract attention.
And then we put a speed controller on it, so people can control the speed that we want. And it is environmentally friendly because it doesn't use wooden sticks.
