Color Reference

K1 · Deep Sea Blue

A richly saturated blue, like sunlight piercing clear deep water — the most vivid blue in the range.

Italian Mosha Suede (Signature K Series)——A velvety suede texture that absorbs natural hand oils with use, developing a one-of-a-kind warm sheen.

Please note your preferred colour in the order notes (this doesn't affect price); see "Select Option" on the right for the actual order spec.

Swatch dots are an approximate colour reference only — actual colour will vary slightly from the leather itself; photos may also differ slightly due to lighting and screen display.

"In a cold tech age, rediscover a sense of warmth in the tools you create with." This laptop sleeve has an envelope-style silhouette that's clean and understated. It's made from a single large piece of leather, hand-stitched one stitch at a time to remove unnecessary layers and extra seams for a seamless, unified feel. Extra leather reinforcement is added to all four interior corners for added protection and a sturdier shape. It closes with a leather strap and a large brass snap button.

Packaging

We believe packaging is more than protection — it's an extension of the design. Every piece comes with the following, so it feels considered whether it's a gift or a treat for yourself:

Architectural Kraft Gift Box：An industrial-style rigid box, hand-tied with natural jute twine and a debossed leather tag.
Care Guide：A care guide in a textured black envelope, so you can keep your piece in its best condition with confidence.
Hand-Marbled Wax Seal：Every wax seal is hand-mixed by our craftsman, giving each one a unique marbled texture as the final mark of authenticity.
Branded Cotton Dust Bag：Made from natural cotton and linen, for easy everyday storage and surface protection.
Custom Grey Tissue Paper：Wrapped inside with hykc-branded tissue paper, so every layer carries the same architectural aesthetic.
