Let’s be honest: the absolute best part of being anywhere near a convenience store in Japan is that magical moment of unwrapping a fresh onigiri. It never gets old.

Now, the brilliant stationery wizards at King Jim have officially bottled that exact dopamine rush for your workspace.

King Jim's new line of stationery is known as Jim Mart. If you've been to Japan the design look extremely close to the design of food products found in the Japanese convenience stores. Just replace the "Jim" with "Family."

Jim Mart's delightful new lineup takes iconic Japanese conbini staples, and turns them into the cutest, most tactile desk gear imaginable.

Peel, Open, Erase: The Desktop Snack Break

Let’s look at the mechanics here because the design team clearly understood the assignment. The Jim Mart collection comes in 2 main types. The onigiri cases, and the letter set.

Jim Mart Onigiri Eraser and Paperclip Case

Let's first talk about the onigiri eraser and . The onigiri cases come in two variations: the onigiri eraser set and the onigiri paperclip set. The erasers or paperclips are inside the onigiri case which is then inside a seaweed paper which is then inside in a plastic wrapper that you peel open just like the real deal (Japan and their wrappers).

To open it, just follow the numberes. First you'll pull the top center tab down to split the wrapper in half, then pull the two halves apart revealing the onigiri case. This will definitely bring back memories for some. The only downside to this is that once you open it the first time, that's it (I guess just like a real onigiri).

Savor the moment, because you'll get to open it only once

Each variation come in 4 different flavors like Salmon, Pickled Plum, Tuna Mayo, and Pollock Roe. The sturdy little triangular case doubles as a mini storage box for all of your tiny things like SD cards, paper clips, and even stitch markers if you're crocheting.

What you get when you purchase these cute stationery is 1 onigiri case, and 6 erasers or paper clips (2 designs - 3 each). Just make sure you buy the right one because their come as either the eraser set, or paperclip set. Luckily, each one costs almost the same price as an actual onigiri.

Jim Mart Letter Set

The other lineup is their letter , which also has the convenience store tear-open packaging and adorable flavor labels. Unlike the onigiri cases, this set puts you on the other side of the counter, giving you the role of letting someone else open up the item.

Your friend, family, or loved one will love opening this up. Hopefully not more than reading your message.

The letter sets come with the onigiri packaging, but also has fried chicken and their corn dog design. Unlike the onigiri where you tear open, the fried chicken and corn dog open horizontally. They even give you the tape that conbinis use to close up the envelope to keep your food hot. Talk about attention to detail. Each letter set comes with 2 food items, 2 envelopes, and 2 food sealing tape.

It’s playful, completely unhinged in the best way possible, and honestly the only acceptable way to send a thank-you note to a coworker.

Whimsy Wins the Workspace

Look, work can be a grind, which is why stationery lovers and design nerds are always hunting for things that inject a little personality into the 9-to-5. King Jim totally nails that sweet spot between clever engineering and pure, lighthearted fun.

It’s playful, it’s aggressively niche, and it turns your boring old desk into a fun little Tokyo snack bar. Just maybe double-check before you try to take a bite out of your Tuna-Mayo eraser during a long Zoom call.
