Great prices on your favourite Office brands plus free delivery and returns on eligible orders.

Review: Great item, swiftly received, friendly seller - You know what, it's just a pen ink; but when this turned up in the post, I was in the middle of a pretty terrible Friday at work. So I'd just like to say thanks very much to "M" for the note on the invoice. It really made my day and restored some faith in humanity. Product wise, I've been writing with Fisher Space Pens for over 25 years. Genuinely a super impressive product which features pressurised ink meaning you can write at all sorts of angles and the pen will continue to write. Haven't had the chance to test it in space but can confirm, they've always worked for me over grease and even underwater/over wet surfaces. Comes with a handy adapter to fix most parker pens too.
Review: Wonderful - Really good, writes on anything

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great item, swiftly received, friendly seller
*by S***N on 24 January 2021*

You know what, it's just a pen ink; but when this turned up in the post, I was in the middle of a pretty terrible Friday at work. So I'd just like to say thanks very much to "M" for the note on the invoice. It really made my day and restored some faith in humanity.

### ⭐⭐⭐⭐⭐ Wonderful
*by G***K on 26 July 2025*

Really good, writes on anything

### ⭐⭐⭐⭐ Good price - wish they did fine point
*by D***R on 27 January 2018*

I was really looking for a fine point black refill, but at this price it was worth the change to blue/medium. I've had my Space Ben for a long time and this is the first time I've had to refill it, so I look forward to seeing how long this one lasts. The refill comes with a small extended plastic cap to convert it for use as a Parker-style refill. I know that the Parker design refill is used in many pens, but it did not fit in my daily-use Parker Jotter as it was slightly too wide, so if anyone is intending to use this in an actual Parker pen, be aware that it may not fit. Otherwise, good product, good price, good delivery time.
