Buy pre-designed items

There are some sample items in our shop.
We tried to assemble some nice looking products, like this one.

If you like them just choose the Color, Size and Quantity and "Add them to your Cart".

Make your own

In our store you are not limited to the already existing products.
Instead, you can create your own T-Shirts, Hoodies, Mugs, Accessories, etc.

If you want to use an existing product as a base, just click the "pencil" button on the product page to open the Customizer.

If you'd rather start from scratch, click "Customize" on the top right menu.

After the Customizer is started, you can use the following functions.

Buttons explained below


You can choose any product our print partner has in it´s catalogue.


You can choose different high quality graphics which we have uploaded for you.

Most images are PNG files, but some of them are Vector files.

Both graphic types have different advantages and can be used for different print techniques wich are described below.

Quick overview of the differences:
- The Image can have multiple colors (photos are possible, too).
- They get printed in the colors that are stored in the PNG.
- Can be used for these print techniques:
Digital Direct, Thermo sublimation, Digital Transfer/Laser Transfer
(The print partner decides which print technique fits to which product.)

- The Image can only have 3 colors
- You can change the color of the item. Depending on the Vector graphic, you can change up to 3 colors.
- Can be used for these print techniques:
Digital Direct, Flex Printing, Flock Printing and Special Flex Printing.
(You decide which technique is used for the clothing.)

Vector files can be recognized by the colored circle right beneath the image.

There are also hundreds of designs available from our printing partner.
Our [THR] Designs can always be found at the top of the list, or simply by reopening the design window.


Of course you can also use your own graphics.
(It would be great if we share great images in the #shop channel in Discord.)

Laundry test for best print results

Before products are added to our range, we make sure they live up to our high standards with thorough testing. Products and prints must go through a cycle of ten washes without losing color saturation, before we consider them satisfactory for our customers. We accept nothing but brilliant prints with realistic color reproduction. This is the best way to establish quality assurance.
