The first impression

Packaging and contents

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The laundry bag set of 2 from the Naturstube brand makes a good impression at first glance. It is supplied in a classic shipping box that is adequately secured against unintentional opening and therefore offers additional protection. The sustainability of the packaging is particularly positive, as only recyclable and renewable materials such as paper and cardboard were used for the shipping box.

The contents of the package are complete and in perfect condition. In addition to the laundry bags themselves, the package contains a thank you card with contact details. Overall, the laundry bag set of 2 from Naturstube leaves a very positive impression. The packaging is robust and durable and the contents of the package live up to expectations. Instructions for use are not included, but as the product is self-explanatory, this is not necessary.

The set contains two bags with a capacity of 45 liters (50x70cm). However, the set is also available with a capacity of 100 liters (67x87cm).

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

The use of the threaded drawstring enables easy handling and secure closure of the laundry bags and guarantees that no laundry can fall out of the bag.
Thanks to their size, the laundry bags are suitable for everyday use. Even after a slight shrinkage, 5 kg of laundry can be filled without any problems.
Another advantage is that they are easy to clean. After use, they can be washed at temperatures of up to 40°C , which means they can be reused hygienically.
All in all, the cotton laundry bag set of 2 offers an environmentally friendly and stylish alternative for storing laundry.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

On the Amazon platform, consumers rate the product with an average of 4.6 stars. One common complaint is that the bags shrink easily after the first wash. Many customers like the fact that the sustainable laundry bags are very robust, well made and of great quality.
