UNI LAMY Safari Jetstream Insides: LAMY Design Meets Jetstream Ink

Introduction

The Safari is one of the most recognizable pen designs around, and now it ships with one of the most trusted ballpoint ink systems in the market. The UNI LAMY Safari Jetstream Insides is the first LAMY product released under UNI, following the two companies becoming a consolidated group in February 2024. As the “Insides” name suggests, it comes fitted with a Jetstream refill from the start, and that pairing makes a genuine difference to how the pen writes.

First Impressions and Packaging

Ordered online, the pen arrived in a dented box with the pen packaged separately. That is a shame for a product that marks the first time these two brands have come together. A refreshed package or logo treatment would have made the moment feel more special.

The barrel carries a removable label with the new product name. It is reassuring to have some identification, but a printed logo or product name on the body itself would have been the better choice. Once the label is peeled off, there is no way to tell this Jetstream-equipped version apart from a regular Safari with a Jetstream refill dropped in, which undermines the reason to buy this pen as a complete unit. A permanent mark on the barrel would have raised the product’s value and given even existing Safari owners a reason to want this version.

One detail in the box: the included warranty paperwork describes the purchase as a LAMY product, with the Japanese pen maker’s name printed below. A small touch, but an interesting reflection of how this collaboration is presented.

Design and Grip

The Safari’s identity is unmistakable. Every angle carries the silhouette’s signature elements, and the accordion-style wire clip still feels distinctive even now that such clips are more common. This review unit is Dark Dusk, a limited-edition color with a glossy coated finish and a deep blue that leans toward violet. It looks sharp.

There are seven colors in total: Vista Blue, Red, Umbra, Yellow, Dark Dusk, and Sunset, with Dark Dusk and Sunset being limited editions. On those two colors only, the grip matches the body color. It is worth noting that recent dealer catalogs have been inconsistent about whether these two shades are labeled as new colors or limited editions, and some shops sell them as regular stock, which has confused retailers. The limited-edition reading appears to be the correct one.

The grip has three sculpted facets and a stopper ridge that keeps your fingers from sliding further down, which suits writers who grip low on the barrel. The body is fairly slender at 10.5mm, and the whole thing measures 138mm and weighs 13.5g with a high center of gravity.

One quality concern: the resin body is molded in two halves, and the parting line runs exactly along the curved corners of the grip on both sides, leaving slight burrs. It is not sharp enough to cut skin, but the texture is noticeably rough on both sides and could use better finishing.

Refill and Writing Performance

Unscrewing the front cap reveals a surprise: the spring is a vivid orange. It is a bright, cheerful detail. The included refill is a Jetstream F in 0.7mm, and an EF 0.5mm option is available separately if you prefer a finer line. Note that this pen uses the M17 refill rather than the conventional M16.

The knock button is large and easy to press, with a firm, positive switch feel. The tip retracts slightly further than ideal, which takes a little getting used to, but the more important finding is how stable it is. There is almost no tip wobble at all, which directly benefits the writing feel.

On paper, the pen glides smoothly with no stutter. The Safari and Jetstream combination genuinely suits each other. If there is a personal quibble, it is weight: at 13.5g it feels a touch light, and a slightly heavier pen would suit some writers better. That said, the balance is good and the pen is easy to hold for longer sessions.

Who Should Buy It

This pen makes the most sense for two groups. First, anyone who has always liked the Safari’s design but hesitated because of the stock refill experience. The Jetstream ink removes that barrier entirely, and it may well prompt a closer look at other LAMY models going forward. Second, existing Safari owners who want the strongest possible ink in the body they already love. The main hesitation is the label-based product identification, which does not reward buying the complete pen quite the way a printed logo would.

The price is 3,630 yen including tax in Japan, and the color range is broad, with two limited finishes for those who want something less common.

Buying Advice

If you decide to pick one up, choose the standard colors if you want a safe long-term purchase, since the limited editions are genuinely limited and availability may vary by shop. If you write with a low grip, the sculpted three-facet grip with its stopper ridge is a real advantage. Check the grip corners on arrival; if the molding line bothers you, an exchange is reasonable given the finish inconsistency.

Conclusion

The UNI LAMY Safari Jetstream Insides delivers the most straightforward version of what this collaboration promised: LAMY’s beloved design with UNI’s strongest ink, released quickly and in the form people actually asked for. The shortcomings are real but fixable. The peel-off label instead of a printed logo undersells the collaboration, and the grip burrs need better quality control. Neither changes the core story, though. This is a comfortable, smooth-writing pen with an iconic look, and it is a strong sign of what the combined company could produce next.
