Lihit Lab Lunlun 665 Paper Pen Case Review: A Soft, Paper-Textured Case With Real Protection

Introduction

Lihit Lab’s Lunlun series is best known for its large-capacity pen cases, and the Lunlun 665 Paper Pen Case continues that idea with a twist: an exterior finished to look and feel like paper. Priced at 2,090 yen tax included, it sits in an accessible range for something this well built. This review covers the design, the interior layout, how it performs with a realistic load of pens and small tools, and the few points worth weighing before buying.

First Impressions and Design

The Paper Pen Case comes in four colors: brown, grey, white, and black. Every one of them looks considered, and the brown in particular carries a strong vintage character. The unit reviewed here arrived in black, which is not a flat black at all; the zipper section is grey, and that two-tone contrast is consistent across the whole color lineup.

The defining feature is the texture. The surface is designed to evoke the soft paper wrapping around freshly baked bread, and it genuinely reads as paper at a glance. In the hand it is soft and pleasant to touch rather than stiff. The oval zipper pull is a Lunlun original part, with a sculpted, three-dimensional feel that feels sturdy. The zipper itself is a coil type, and while it runs smoothly in straight lines, it can catch slightly at the corners. One underrated detail: cases with two zippers often rattle noisily when carried, but this one is noticeably quieter than most.

Inside the Case: Storage and Layout

The interior is split into three zones. The left side is a full-height mesh pocket, suitable for sticky notes, a ruler, and small accessories. It is fairly deep, which means shorter items can be a little awkward to retrieve. The right side has a five-pen holder made from elastic bands: the rightmost loop is narrowest, the middle three are medium width, and the leftmost takes thicker pens. The base under the loops is firm and well supported, unlike the flimsy bases found on some competing cases.

Behind the pen holder is a free space with substantial capacity, easily room for around ten pens. Along the top edge there is a slot sized for erasers; a large eraser fits, or two smaller ones side by side. The sidewalls are where Lunlun quietly stands apart: padding is built into the fabric, the edges are thick and firmly finished, and the whole case is soft yet dense and resistant to crushing. It is the kind of design that suggests it was drawn up by someone who genuinely loves stationery, and it keeps your pens well protected.

Everyday Use: What Fits, and How It Feels

Loaded with a casual everyday carry, the case handles a full spread comfortably. The five pen loops took a limited-edition drafting pencil, a second mechanical pencil, a slim 0.3mm pencil, a clipless full-metal hexagonal ballpoint (the elastic loops hold clipless pens securely, a real advantage), and a twist-action multi-pen in the wide slot. The mesh pocket swallowed an aluminium and wood ruler, an extra-smooth ballpoint, a customizable five-color multi-pen, and a compact utility knife. The free space held two erasers and a small memo pad.

The packing experience is genuinely satisfying. When the memo pad sits at the bottom of the free space, the closed pen loops press down and hold everything in place so nothing shifts inside. Interestingly, once loaded, the zipper ran even more smoothly. Fully packed it feels snug, but it closes with room to spare, and for most people the capacity is more than sufficient.

Things to Consider Before Buying

The only real quibble is the mesh pocket. It works fine as is, but its depth makes small items slightly hard to fish out; long items fit better in the free space anyway. A layout that split the pocket into two shallower sections, or ran the mesh across the full height with a horizontal opening, would make small accessories easier to grab. Beyond that, there is little to fault: the case already feels highly polished.

Buying Advice

If you want a pen case that looks distinctive, protects its contents properly, and swallows a full daily kit without bulging awkwardly, this is an easy recommendation. Among the Lunlun 600 series designs, the paper-textured version may well be the most appealing of the bunch. The high free-space flexibility means different users can organize it in different ways, and that thick, soft padding is the detail that keeps drawing you back.

Conclusion

The Lunlun 665 Paper Pen Case combines a charming paper-like finish with genuinely thoughtful construction: quiet zippers, firm pen loops, thick cushioned walls, and flexible storage. Its minor pocket-depth quirk is easy to live with. For anyone upgrading a daily carry of pens and small tools, it is well worth a close look.
