Biannual advertisement: SG Green magazine
We advise on the SG Geen magzine published by SGBC biannally, since September 2019.
We also distribute copies of SG Geen magazine with our test report, to both Singapore and oversea customers, to showcase the green building initiatives in Singapore.
Corporate gift


We also distribute inflatable travel pillow and notebook to our customers, for their more comfortable journey or more productive workplace.
