## Description

Fisher Space Ballpoint Refill- Green Medium : desertcart.co.uk: Stationery & Office Supplies

Review: Functional and Excellent - I don't know what "sheerness" means with respect to ball-pen refills. 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!
Review: Good, reliable work-horse of a pen refill. - I've been using fisher pens for a few years now since I was introduced to them by a colleague at work. My job involves writing in paper notebooks in all sorts of weather conditions - from freezing temperatures, to peeing rain. The way the fisher cartridges are designed means that these write even on wet paper, at any angle, and in the lowest of the low temperatures. And before any smarties-pants suggests I use a pencil - i'm not allowed to!! I initially used these in proper branded fisher barrels, however I have found that I prefer the feel in my hand of some of the parker pen barrels. These cartridges come with a little plastic attachment which means they fit perfectly into the parker pen barrels with no issues. My gripe with the fisher barrels is that they tend to be a bit over-designed - probably in an effort to make them more reminiscent of the space race, often at the expense of writer's comfort! These come in a plastic blister pack, mounted on card, for anyone interested in how these arrive.

A: Not sure if the refill includes the little plastic adaptor.

### ⭐⭐⭐⭐⭐ Nice green
*by S***E on 8 May 2024*

This shade is to green what blue-black is to blue, a good, mid-range colour, and it doesn't give off the 'mad' vibes associated with green ink. It is sane and pleasing, just green. Ideal for crosswords, calendars - and writing to your MP. As to the quality, it's a standard, branded Fisher Space Pen refill. They're very good.
