Capitalized, it's a seaside town in Kent, uncaptialized it's something to do do with stockings, however I've given this 5 stars, because these are good. I've given 5 stars for "thickness" too. It says its a medium thickness nib, and its seems to be just that. These fine items with a little plastic Parker adapter, which means that that old Parker biro found in a deceased relative's effects, 40 years old, and with a dried-out and dribbled refill, can be given a new lease of life. In fairness to Parker, the original refills are not actually intended to last 40 years upside down at the bottom of a drawer, stay working and not leak, so you can't really blame them. Space pen refills are intended for durability, indifference to gravity, and effective sealing. I can't say whether they will last 40 years, the last space pen I bought was only 30 years ago, and its probably at the bottom of a drawer somewhere, and (if I ever find it again) I'd be amazed to find it didn't still work. For the pen-conscious, you can refurbish and upgrade a classic pen to better-than-original spec and consider yourself fashionably retro. For cheapskates, you can get a classy old biro working again to give yourself a wholly-spurious appearance of sophistication, and save yourself the effort of acquiring nasty little disposables from Argos, betting shops etc or even (shudder!) buying a packet of cheap'n'nasty supermarket pens. For people like myself, who leave pens on any available horizontal surface, keep them loose in their pockets, or in that ash-tray thing in the car with the corroded change for parking meters and decomposing sweets and still expect the pen to work, a space pen is ideal. They can be kept under grotty conditions, will write on grotty surfaces, and they stay working. I bought three of these to resurrect a trio of my Dad's old Parkers from the 70s. I can see one of them on the desk at the moment, but dunno where I have left the other two, but I am confident that, when I find them, they will still work. On that basis, space pens are good value for money, so I gave them five stars for this. Functional and excellent, as I said in the title!
