Can you recommend me a nail buffer?

[70isaLimitNotaTarget]

I can't wear any nail product at work but a couple of times I've been out in big shopping centres and someone has demonstrated a nail buffer on one of my nails.
Really nice, quick, glossy and no peely laquer.

Where can I get something to do this?
Any recommendations?

Leighton Denny one is fantastic! Marks and Spencers and QVC have them.

The Body Shop, £2.

I bought a Leighton Denny "Trio" buffer (Buff Ridges/Smooth Nails/Miracle Shine) and just used it, I now have a lovely shine (but I'll need to keep it where I'll remember to use it. By the computer probably )

I used to have the Leighton D 4 sided one but it was quite chunky. This new one is more like a thick emery board, thinner and flexible.

I second the Body Shop one,best I've tried.

Boots do one it's really good too

Boots/superdrug etc do various brands of them quite cheaply, I wouldn't spend the cash on those Dead Sea ones touted in shopping centres as they are no different b
