Measure correctly

The best way to measure your device is with a ruler. We need the dimensions in mm.

IMPORTANT: If you tell us your exact phone model, we do NOT need any measurements. This also applies if you also use a mobile phone case with a maximum wall thickness of 2 mm.

Nice & fair

our philosophy

A noble & simple design and high-quality workmanship are very important to us. However, our idea of appreciation begins with the materials, which are selected according to fair and sustainable criteria. With the production in our own workshop and the internal customer service, we consistently continue and implement this philosophy.

Gute Materialien: Wollfilz und Bio-Baumwolle

Simply good

Our high-quality materials are the basis for your new cell phone case. Our wool felt, organic cotton and cotton yarn are produced in Europe.

Handmade in Germany

Handmade in Germany

We manufacture your custom-fit mobile phone case as soon as it is ordered. In this way we avoid "dead stock" and achieve efficient use of materials.

Sent with love

Sent with love

After 2-3 working days, the mobile phone case will be delivered to you at home, wrapped like a gift. Our grass paper packaging conserves resources and is plastic-free.

Excellent edge protection for your smartphone

The cell phone case LET has a material thickness of 2mm and thus protects your cell phone perfectly. Felt made from sheep's wool is a natural material with very good shock-absorbing properties. On the edges left, right and below next to the seam there is another 3mm felt that serves as a crumple zone and absorbs the impact forces in the event of impact.

Simple & elegant

With our mobile phone case you have timeless protection for your smartphone. Completely no frills. But with a subtle eye-catcher inside. Our organic cotton is printed with exclusive Smukbird designs.

Perfect fit for you

The device doesn't just slip out of the cell phone pocket. We tested this several times when calculating the bag size. This means that it does not need a clasp and remains minimalistic and stylish.

At the same time, the size is optimized for optimal handling. So you can easily remove and insert your phone.

Wool from trustworthy shepherds

The wool for our felt comes from sheep from New Zealand and Australia. The wool is mulesing free. Mulesing is a controversial process, which is unfortunately still practiced in Australia, but only with Merino wool sheep. The Australian wool from our German felt producer is 100% free of merino wool. This creates a mixture of New Zealand merino wool and Australian non-merino wool, which also has an effect on the particularly good and consistent quality of our felt. It is even, stable and pleasant to the touch.

Wool from trustworthy shepherds

Fair organic cotton

The production of organic cotton is GOTS certified and is subject to the socially and environmentally compatible GOT standards. The printing takes place within the EU in Poland at a modern textile printing company.

The organic cotton yarn is produced in the tranquil Netherlands.
