In order to let others know more about the partnership and connection between the two founders— Tam and Kevin of Madult via the stationary, we used the dual 3D eyeglasses idea to produce a fun and interesting stationery collection. The color BLUE represents Kevin and RED represents Tam and with their personal information printed on the envelopes, letter paper and name card, you will need Kevin’s PVS plastic slip and vice versa to view Tam’s information from, the same way if you want to read Kevin's information. Of course, you can also use it as 3D glasses : )
