No  idea where that hospital is located, and the url doesn't seem to load.

 

In any case, I've bought the orange colored ones at Home Pro.

pharmacy.

In Tai Watsudu I saw huge packets of foam earplugs (200?) for about 300B which is probably cheaper than a pharmacy would be. I remember trying them once 30 years ago and could never get them into my ear. Luckily those ones only came in a packet of two. Silicone ones are the type to get, I think.
