3M Nexcare Blister Waterproof Bandages, Bwb-06, 6-Count, One Size [Price is Per Each]

It seems so silly to get excited about plasters... but these are extraordinary. They are very slim - a fraction of the depth of a regular plaster, so they fit very smoothly to the skin, they are far more flexible so good for hands or feet, and have better sticking power than the usual ones. They're better shaped, so that there is a fair amount of sticky stuff around the gauze. You DO have to read the instructions though, as there is a removable white edge on the top surface which comes off last. (It gives some rigidity so you can handle the plaster effectively.) Who'd have thought something could be reinvented so successfully.

First discovered these on a holiday in the States and very pleased to find them available here. They really stick and are totally clear so very discreet.
