The only screen protector for Nexus 7 that MobyShop carries, is the Clasy Screen Protector. Clasy is a Korean brand and the screen protector itself is Made in Korea. It is pretty cheap, I only paid S$12 for it!
The packaging is extremely simple, it contains just the screen protector and the microfiber cloth!
SGP do have screen protector for Nexus 7, but unfortunately MobyShop doesn’t carry it. I am guessing maybe the distributor of SGP products in Singapore doesn’t distribute them in the first place.
For the price of S$12, I think the Clasy Screen Protector is pretty good! After few week of use, I have no complains yet!
