I work in a supermarket café, I have to wear blue plasters. In my experience the ones I used to buy from Tesco's lasted way better than the ones we were provided (I say were, no one has replenished our first aid kit for months, what they think we're supposed to do when we run out of plasters is beyond me, as the shop I work in doesn't sell blue plasters either!)
I wandered around every shop that sells plasters in my town and no one sells them anymore! Why not? They used to! grumble The internet it is then, hopefully I can find some that aren't rubbish, (as in, you put a plaster on, then the first time you wash your hands it falls off. Grrrr.)
