What's Unique about Us


We have our own workshop capable of doing basic wood and metal working
which enables us to make models, prototypes to check form, structure and mechanism BY OUR HANDS.
We don't just sit in front of PCs and do design, we use both our brain and hands,
which we think, can make a major difference when it comes down to real product.

Although we are not experts in programming, we often combine programming skills in our work,
because, especially for GUI, there are a lot of scenes where we can boost effeciency using bunch of
our original programs which consequently benefits to swift response to costumers offer.
