All items are built and designed by me, Greg Tay. Products are made using CNC machines and CADCAM designed by myself. I am a Singaporean based in Singapore now and have be building quality DOF adapters and accessories since 2008. All products are shipped from Singapore unless I move to another coountry to work. I have an engineering background but I spent 20 years in the Broadcast industry and I am an expert in 3D animation, motion graphics, visual fx, editing and videography. I run this store alone and have upgraded from my blog store which is a mess. THANK YOU FOR YOUR SUPPORT. You can text me on my mobile phone +6591087690 but please do not call.
