The Perfect Fit and Best Grip


The case of KANN ULTRA is made of high-quality vegetable tanned leather from BADALASSI CARLO and CONCERIA WALPIER, and boasts a high degree of perfection that matches the design of KANN ULTRA.

The case is available in two colours and is wrapped around the entire product, providing excellent protection and the best grip with a perfect fit.



Badalassi Carlo, a tannery founded by CARLO BADALASSI, who was a professor at a leather school in the Santa Croce region, has been producing leather for more than 40 years by integrating the traditional vegetable leather processing method developed in Tuscany with his unique theory and technology.
Vegetable leather processing is an eco-friendly leather manufacturing method that takes a long time to complete by tanning leather only with tannins extracted from plants.


Established in 1973 in San Miniato, Tuscany, Italy, Walpier Tannery has been in business for three generations and has a long tradition of making leather products based on their highly regarded vegetable tanning processes. The tannery uses only 100% raw hide leathers imported from France and is a member of Vera Pelle, Italy’s association of vegetable-based leather tanners.
Walpier's vegetable tanning is a traditional leather processing method handed down from father to son for centuries in the Tuscany region. The tanning process usually takes 40 days and is a process only practiced by Italian tanners of the world.

[Buttero] Navy Case

The Navy color case of KANN ULTRA uses Walpier's Buttero leather. Buttero leather is a leather made by milling the leather to make it soft and natural on the surface. Buttero leather, like other leather used by Walpier, is manufactured from the finest French hides, so the texture is dense, and the surface is smooth.
Due to Walpier’s highly regarded method of vegetable tanning, the Buttero leather boasts excellent color with a perfect surface finish and is highly resistant to scratches. This allows manufacturers to utilize the original texture of the leather without the problems normally associated with other vegetable processing.

[Minerva] Black Case

Minerva leather, unlike Minerva Box, is a plain, un-milled leather that looks matte at first, but as it gets used, the color deepens and the luster increases, so you can see and feel the change over time.
Minerva is a vegetable tanned leather made using the unique Vacchetta method from Tuscany. At first, the leather looks matte with a lack of sheen, but over time it adds a natural luster and deepens the color. This is because there is no artificial coating on the leather surface, so the gloss rises naturally from the oil contained in the leather itself as it is used. As with other vegetable tanned leathers, Minerva is especially beautiful with time.
