1, take into account the lens and flash light 2, large opening humanized design 3, quality toughness Radium cavving principle, namely the laser processing principle:1, the use of laser emission of high intensity laser beam focus in place, and let the material oxidation and carry on the processing.2, the effect of playing mark is through the surface physical evaporation show deep material, or through the light energy cause surface physical chemistry physical change out of the mark, or through the light burned part substances, and scribing trace, or through the light burned part material, show required etching graphics, text.  Quality features:01, take into account the lens and flash lightAccording to the demand of customer, using the ellipse hole, and taking account of the lens and flash light, avoid using gourd hole flash light narrow surrounding space , lead to take pictures imaging quality is not high.02, large opening humanized designTop and side with large opening design, let you barrier-free use headphones hole, convenient touch volume key. The corner process clean and round, and seamless joint with mobile phone.03, quality toughnessISUN uses the south Korean import special PC material, the quality of the material is very thin, not changeful form, and a distorted to roll up also won't break, not easy in the dismantling of rupture, can be enough to protect your mobile phone. Productive Area     Certificate
