Uni Pure Malt Jetstream Single Review: 0.5mm Wood Pen

Uni Pure Malt Jetstream Single pairs black 0.5mm Jetstream ballpoint ink with a barrel made using reclaimed whisky-barrel oak. This is the SXN-PM-05 single-color model in Marukaku's catalog. It suits someone who wants one dependable black-ink pen with a distinctive natural-wood body.

Is it 0.5mm or 0.7mm?

The current Marukaku listing and Uni's SXN-PM-05 product specification both identify this Single model as 0.5mm. The Pure Malt 4&1 carried by Marukaku has 0.7mm ink balls and a 0.5mm mechanical pencil; those sizes should not be mixed up. Check the exact model on your order.

Can the black ink be replaced?

The catalog lists SXR-5 as the matching 0.5mm refill. Match the printed model number when purchasing a refill; the replacement ink is a separate product from the wooden pen. Wood grain and shade can vary from the product photo.

Single or 4&1?

Choose the Single if you mainly write in black and want a straightforward ballpoint. Choose the 4&1 if you need black, red, blue, green and a pencil in one body. A larger set of functions adds little value if you never switch colors.

Evidence and limits

This article explains the published model specifications and a practical choice. It does not contain a measured drying or grip test and does not promise the same wood grain on every barrel.
