Lean design

Because iPhone is like "iPhone".

Covering the iPhone with its beautiful texture, seamless continuity of glass and metal, and the designer's commitment beyond conventional wisdom, it is not appropriate to cover the iPhone with plastic or synthetic leather.
However, if you leave your iPhone naked, you are worried about scratches. With a beautiful and durable SYRINX sleeve, you can protect it from damage and scratches when not in use, and enjoy the true beauty of your iPhone when you are using it.

Minimal design just to sandwich

The design concept is "to eliminate all waste".
It is sandwiched between a piece of fine leather and adds only minimal stitching. A baptized design that can't cut anything further.
With minimal stitching, you can connect and listen to music or operate buttons. You can also use the iPhone upside down. The sound hole is hardly closed, and the sound is not filled.

Lean design

Just fit the more you use

Most of the distributed leather products make leather thinly. This is because thinner ones maintain uniform quality, workability is better, and products are lighter and thinner.
However, we thought that the best part of tanning leather could be enjoyed in heavy leather. And, if possible, the original thickness. Near the floor (the back of the leather) is the most oil-soaked. If you cut the floor, the benefits of oily leather will be greatly impaired.
The only way to design an iPhone case with an original thickness that varies in thickness is to design it tightly, and there is a risk of complaints and returns. However, tanned leather grows when tightened. And in fact, it shrinks when loose. In other words, the more you use it, the more it fits and doesn't get too loose after years of use.
Leather that is thinly made and loses its internal fiber loses its original resilience and only grows. Making products that require precision with original thick leather has never been possible with conventional wisdom, but it really makes sense.


The length may shrink by about 3mm, so we calculate it and make it slightly longer. The width also tries to shrink, so it just fits and does not fall when inverted. To take it out, simply push up your iPhone from below with your finger and you can take it out smartly.

Durable thick leather protects from damage


No matter how beautiful it is, there is no point in protecting your iPhone. Approximately 2mm thick leather filled with fibers protects the iPhone firmly. Guards corners that are easily damaged when falling. The open corners also make the leather slightly larger to prevent glass breakage.

Protect from battery deterioration

Lithium-ion batteries deteriorate due to heat generation. Therefore, if you charge the battery with the case attached, it will be difficult to dissipate heat and shorten the life of the battery. However, removing the case every day is a tedious task.
In order to protect your iPhone from battery deterioration, this product that can easily take out your iPhone is exactly the best.


Attention to detail

The attention to detail has resulted in a sophisticated appearance.

1 Brand logo

The brand logo is engraved small on the inside of the case to make it as inconspicuous as possible, so as not to impair the simple design.


XNUMX Polishing Koba

The finish of the leather edge is polished.
I am worried that the painted edge will crack or peel off over time. It takes time, but the polished edge does not have that worry, and the more you use it, the more it tastes.


Deepening color gloss, Vachetta leather

"Vaketta manufacturing method" transmitted to the Tuscany region of Italy from the early 9th century. We adopted Tempestee's Elbamat leather, which continues to preserve that tradition. Leather tanned with natural tree tannins and slowly impregnated with oil.
