About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

This product was sent in a shipping bag made of brown recycled paper.
Inside the bag was the product box, which was very well matched to the size of the product.
The folding cards and envelopes inside the box were packed in plastic . It would be desirable for the manufacturer to consider a more environmentally friendly packaging option.
Instructions for use are not included with the product, but are not required as the product is self-explanatory.

When you pick up this product for the first time, you immediately notice the even finish of the envelopes and cards.
The individual elements can be stacked easily.
With regard to the surface, it was found to be very pleasant to the touch and an initial test with a pen showed that the cards are easy to write on without the writing smudging.
The thickness of the cards feels even, so it can be assumed that they fold well .
No conclusive statement can yet be made regarding stability , but the paper thickness seems appropriate and makes a high-quality impression overall.

Practical tests have shown that the material quality and thickness of the folded cards and envelopes are appropriate.
The individual components have good stability and can still be optimally folded – especially thanks to the prefabricated fold seam – so that they can be used in a variety of ways.
In terms of colour uniformity, it should be noted that both the folded cards and the envelopes are a uniform white colour that is free from stains. The individual components have an even and high-quality appearance.
Thanks to the appropriate thickness, practical tests have also shown that the material is relatively tear-resistant – minimising the likelihood of accidentally creating small tears or tearing corners.
The odour test of the product was positive – the individual components smell absolutely neutral.
In the practical test, this set of folding cards and envelopes impressed with its good material quality and pleasant writeability. This is a product that can be used in a variety of ways and for a wide range of occasions.
