Adult size is abt $3.6 per pc while Kid size is abt $0.6 per pc.

Not sure why kid size is so much cheaper .
I hv made my purchase thr 3M agent. Hopefully can get the stock by today ( at least for kid size. Adult is all stock out & hv to wait for Monday for delivery )...

Raffles Med clinic is also out of stock !
