Imagine reading what you wrote at 19.

Ava writes everywhere. On the stairs at a dorm party, with the music going. On a dryer in the basement laundry room. In the back row of a lecture hall. Once, flat on her back on top of a concert crowd. In the library two friends lean over her shoulder to ask what it says. It says who she sat with.

Now try yours. The girl down the hall, the one you told everything to. The song. The thing you were absolutely sure about. You can see the hallway, and you can't get the words back. One woman texted us in October, "I haven't journaled since I was 19 when college became all-consuming. Then career, marriage, and raising kids." That's most of us.

Nobody writes down the big moments in the right words anyway. What you'd love to read now is the dull stuff: what you ate, who you were mad at, what you thought you'd be doing by thirty.

"this one reminds me of highschool when EVERYTHING got written down!" one woman commented in October. Another told us what she wants from hers: "Go back later on to read where I was at in the moment." That only works if somebody starts while it's still the boring present.

It arrives in a linen travel bag. Inside: the premium leather cover, two 76-page inserts (one lined, one blank), a clear zipper organizer insert for the tickets and notes you want to hold onto, and the charm you choose. US shipping is free. Nothing to wrap, if it's going to someone else.

Not in the box: a pen, the clips, the ribbon, the stickers and the extra charms you see in the video. Grid and planner inserts are sold separately.

There are no dates printed anywhere in a Momento, and that matters most at 19, when nobody's week goes to plan. Finals. A breakup. A month of nothing. She comes back to it in April and the next page is just the next page, with no row of empty squares saying she quit.

The same goes for you. Skip a year. It'll wait.

When an insert is done, it slides out of the cover and a new one slides in. Refills start at $12, about 76 pages each. Freshman year goes on a shelf in her own hand and sophomore year starts in the same cover. The lifetime warranty covers the binding, the cover and the hardware.

One woman told us by text in October that she wants three, in separate colors, "one for me and one for each of my daughters."

The Pocket cover is 4.25 x 6.89 in (108 x 175 mm), with pages of 90 x 163 mm. It's the one for a backpack or a jacket pocket. The Classic is 4.72 x 7.87 in (120 x 200 mm), with pages of 105 x 190 mm. That's the one for longer entries at a desk.

Will your own inserts fit? Traveler's Notebook Passport inserts fit both sizes. A6 and Hobonichi Weeks fit the Classic only. A5 and B6 are too big for either.

The Momento is 50% off right now: the Pocket from $69 and the Classic from $89. The charm is free, US shipping is free, and you have easy 100-day returns.

You're the kind of person who wishes somebody had handed you one. Choose a size and a charm. If it's for her, write the first line yourself before you give it away: one thing you remember from being 19. Then start yours the same night.
