Two colour choices

A small object designed to feel closer to a keepsake than a generic checkout product tile.

Reveal

Body heat brings the hidden lettering into view, then lets it fade back into the grain.

The concept

The process from invisibility to visibility is a manifestation of longing, time and time again.

As someone who loves reading and is drawn to those who share this passion, I imagined how romantic it would be for two book lovers to exchange bookmarks engraved with each other's names.

By chance, I discovered this thermochromic material. Warm it, and the name of that special person appears — like a quiet ritual of connection, repeated each time you open a book.

Craftsmanship & Texture

Made with intention.

Every detail considered. Every surface deliberate.

Premium Cowhide Leather

Full-grain cowhide, sourced for texture and durability. Ages beautifully with use.

Pattern Embossing

Deep embossed patterns give the surface a tactile, handcrafted quality you can feel.

Font Stamping with Gold Foil

Names and text are foil-stamped in warm gold, pressed into the leather with precision.

Blank name cards included with the bookmark

Handwritten Name Insert

Write the name yourself, then slide it into the back of the bookmark. Each bookmark includes 7 blank cards.

Gift Box Packaging

Each bookmark arrives in a simple black gift box, wrapped with paper and string so it is ready to give.

Two colours

Choose your warmth.

A restrained palette, shaped more like a desk object than a novelty gift.

Colour 01

Light Color Version

A brighter caramel tone with a soft glow, suited to lighter desks and warmer paper palettes.

Colour 02

Dark Color Version

A deeper coffee tone with stronger contrast, closer to a classic leather-bound edition.

Customer notes

A small ritual for two readers in love.

Warm it with your hand and the hidden name appears — a quiet reminder exchanged between two people who read, miss, and remember each other.

★★★★★

I gave one to my boyfriend with my name hidden inside. He warms it before reading, like a tiny message from me.

— Maya

★★★★★

We exchanged bookmarks for our anniversary. Seeing her name appear in the leather makes it feel personal every time.

Questions

Before you buy it.

How fast does it ship?

We ship Monday–Sunday via international express delivery. Orders within the United States typically arrive within 4–10 business days.

Can I send it directly as a gift?

Yes. At checkout you can enter a separate recipient address. Each bookmark arrives in elegant, gift-ready packaging — no additional wrapping required.

How does the temperature effect work?

The bookmark uses thermochromic material that becomes transparent above 28°C / 82.4°F. Simply hold it in your hand or press it against your skin for 10–20 seconds — the hidden name will gradually appear, then fade again as it cools.

Which payments are supported?

We accept all major credit and debit cards, Apple Pay, Google Pay, and PayPal via our secure Stripe checkout.

What is your return policy?

We accept returns within 7 days of delivery for unused items in original packaging. Personalized items cannot be returned unless defective. Contact us with your order number to initiate a return.

How is the name customized?

You write the name by hand, then slide the card into the back of the bookmark. I include 7 blank cards, so you have 7 chances to write the perfect name.

After purchase

How do I insert the card?

What are the beads for?

We included some beads for you. You can thread them onto the two cords to make the bookmark feel even more unique. It also looks beautiful without the beads; the bookmark itself is already lovely.

This is how I threaded mine; you can use it as a reference.
