Temasek Foundation is giving out free masks for Singapore again. This is the 3rd time that they are doing this. The free 3D mask is from ProShield, and the collection starts from 30th November to 13th December.
For this time round, do check your mask size before going down to get them. They have 4 sizes to choose from (S, M, L, XL).
Here is how to measure your mask size. You will need to measure from the middle of your eyes to the bottom of your chin.
And check out where you can collect the mask from the vending machines.
The free mask is black in color. I believe when it is nearer to date, you should be able to get more information from the official announcement or from the website.
