TUMBLER / Product Design


The cup on the table is often knocked over.
Because of this reason, we design the coaster ,which is called TUMBLER.
Its size fits all kind of cups as well as bottles.When you put a cup into TUMBLER,
there is a gap on the side which you could able to set your mug
the weight of the cup will form downward pressure which makes liquid silicone of
TUMBLER flows to both sides. The pressure will then clutch the cup.
In addition, the bottom of TUMBLER is anti-slip,
so you can put the TUMBLER on the car or tourist coach
it can be fixed on the table in any case.
