Muji Aluminium Hexagon Pen

Muji is one of my favourite brands of all time. I’ve had great experiences with most of the things I’ve purchased from Muji, from stationery to food and skincare. Their products are really great quality and available for a reasonable price. Sadly, there isn’t a Muji store where I live, however, they have just opened up online orders for delivery here and I took the opportunity to stock up on a few things. 

Many brands have tried to produce a refillable metal pen that accepts the general Uniball RT/Pilot G2/Pentel Energel gel refills. When browsing through the Muji store the other day, I noticed that Muji had produced their own edition. Made in a smooth hexagonal aluminium, it’s a pretty minimalist option that is once again very reasonably priced. 

I popped a Muji refill into this pen when I first tried it out – a 0.5mm Blue Black and found that it fit perfectly as you can expect. I also tried some other refills I had on hand and this is what worked and what didn’t: 

• Uniball RT – Yes 
• Pentel Energel – Yes 
• Pilot Juice – No 
• Zebra Sarassa -  Yes

Its definitely not the perfect all rounder refill pen, but it fits enough to make it an extremely attractive option, given the price. The Muji refill is also smooth and dark. Its also quick drying compared to say the Pilot G2 which can be quite globby in its ink laydown.   

In hand, being made of aluminium, it is very lightweight and comfortable to use. The brushed aluminium finish makes it a little slippery, especially when my hands are dry and cold. The click mechanism is sturdy and responsive, it makes a very satisfying click noise when used. I also enjoy the minimalist aesthetic that it sports. 

Other (clicky) options that are more broadly compatible include the Bigidesign pens and Tactile turn, however, while these are compatible with more refill options, these are significantly more expensive. If you enjoy using the refills that is compatible with the Muji, I strongly suggest picking one up, its better made and more reliable than some of the pricier options I’ve tried.
