In great condition, this one has a safety switch, when pushed up-the blade hides behind the bar to avoid cuts or damage when on the move. UK 2nd class delivery included in the price.

@Bikerjohn@Boru62 other options are checking eBay for some NOS ones that come up occasionally, some went recently for under £7 inc postage for 8 NOS made in Holland ones which are excellent. You can get them on Amazon as well but the price is a bit too much.
There are some on a BIN on ebay just now £26 for 30 inc postage from Japan. Considering the twin blades seem to last ages, I get 10+ shaves from them, 86p a blade is not too bad. You may get stung with extra RM fees and tax so that is going to put the cost up though.
