The drawback is the high cost, bad injection functionality. (3) acrylic resin buttons is a kind of mild transmittance, transparency of the greatest plastic. Injection creating of the resin works extremely well for most types of 372, 613, 504 and other major home based models, however the light transmission rate somewhat fewer. Excessive transmittance of polymer resin, pure color, so manufacturing buttons, nearly all of such elements to the creation of high chastity, high clear appearance buttons, the look of them is compared to the
