Bought the Spigen SGP GLAS.tR Nano Slim Screen Protector for iPhone 5/5c/5s from MobyShop for S$52, including free application of the glass screen protector.
Do not get mixed up with a similar glass screen protector called Spigen SGP GLAS.t Nano Slim Screen Protector for iPhone 5/5c/5s (note the R, GLAS.t vs GLAS.tR). The R stands for rounded because the GLAS.tR glass screen protector have rounded edges for a more precise fit and hence it is slightly more expensive.
