Easy-to-use / stationery

Theory of the design:
1. This is a kind of double-sided adhesive, with staggered junctions.
2. When using double-sided adhesive, we usually have the problem that there appear
uneven hemlines if we rip the adhesive or difficulty to rip the surface open if we cut the
adhesive.
3. This double-sided adhesive, with a simple 0.5cm rips to separate two sides of adhesive
(please follow the illustrated pictures), can solve the problem mentioned above in order to
be convenient for people.
