A Leather iPhone Case Designed for Everyday Life

Elegant on the outside, practical on the inside. The Belted Diary Magnetic Case features a softly rounded silhouette and a distinctive belt-style snap closure that keeps the cover securely closed.

Inside, three card slots and two additional pockets provide space for up to five cards, receipts and other small essentials. The diary-style design also helps protect the screen while keeping your belongings discreetly concealed.

A removable magnetic clear case adds further versatility. It can be used separately for a more minimal look, with support for MagSafe accessories and wireless charging when detached from the leather cover.

Premium European Leather, Made to Last

Crafted from premium full-grain Shrink Leather, the iPhone Duo case is distinguished by its soft touch and natural grain. The carefully selected calf leather is resistant to visible scratches, while a protective nano glass coating helps repel moisture and everyday stains.

For those who appreciate different leather textures, the wider collection of premium leather iPhone cases also includes Nobile Leather, an embossed calf leather with a distinctive cross-grain finish.

Both materials reflect BONAVENTURA's commitment to quality, craftsmanship and timeless design.

20 Colors to Suit Your Personal Style

From understated neutrals to expressive shades, the new iPhone Duo leather case is available in 20 color variations.

Choose classic tones such as Etoupe and Black, discover richer shades like Blue Cyan, or explore refined two-tone combinations including Greige × Coral Pink and Black × Etoupe.

Each color brings a different character to the signature design, allowing you to choose a case that feels distinctly yours.
