Lip Emerge

In consideration of the same shape of sanitary cup . it's hard to distinguish which cup has
been used . We designed a kind of cup which can change in color because of the special
contact with people's saliva contains salivary amylase . We will add one special material o 2~3 cm at the top of the cup of our product . So when people use this cup to drink . A
colorful lip print will appears on this cup .And we can use this characteristic to differentiate
if the sanitary cup has been used .
