Remember that misuse in minors can cause suffocation.

Maximum wearing time of the mask

The recommendation of the Spanish regulations regarding hygienic masks is not to use them for more than four hours continuously.

The continuous use of the Rewinder mask should not exceed 8 hours. If you carry out activities that involve sweating, great physical effort or use it in environments with poor ventilation, the recommended continuous use is 4 hours maximum.

The recommendations are just that, recommendations, an orientation of use. It is impossible to make a usage guide for each specific case. If you notice your mask is very wet, for example, it's time to change it.

In the case of very short uses (short-term outings, in little-crowded areas, with little exposure to contagion and low activity), it is possible to reuse the mask without first washing it. We recommend ironing it before using it again for greater safety and always, after each wash, iron it to reactivate its water-repellent, liquid-repellent treatment.

How to start using the Rewinder mask

First steps with your Rewinder mask

5 .- Important! Do not iron directly on the logo if your mask has the REWINDER logo printed on it or if it has been provided by your company with its corporate image.

Our materials

Our fabrics

The natural cotton in our designs comes from sustainable sources , that is, it is recycled or grown with less water, pesticide and fertilizer consumption, which increases the profit margin of farmers and reduces the environmental impact of its cultivation.

In 90% of the products, the cotton used is natural cotton free of dyes.

On the other hand, a large part of our products, and more and more, are made with organic cotton .

The fact that all our alternatives to single-use materials are not made with organic cotton is explained by the fact that this cotton is not always available in Europe, it is increasingly in demand and, sometimes, it is scarce. However, and above all, at Rewinder, what we value most is reducing the real impact of our consumption on the environment , so if our regular suppliers do not have organic cotton available, we prefer to wait for it to arrive and use the natural cotton woven by our nearby trusted suppliers, who guarantee its sustainable and fair origin, to buying organic cotton directly from distant countries, because we would be causing an environmental impact that would go against our own philosophy.

Origin of our Fabrics

Because we like transparency, we want you to know that all our fabrics are woven in Europe. We buy 95% from Spanish suppliers and we buy the remaining 5% mainly from Germany.

We fully trust the quality of our raw material and we work hard to offer you quality and design at a fair price.

99% of our manufacturing is done entirely in Spain , mainly in Catalonia and the Canary Islands, because we believe that this is the way to generate industry, employment and the opportunity to strengthen a present with which to guarantee the future.

Our Stamping

The printing we do is done with ecological water-based inks .

One by one and in an artisanal way we print each of our designs on the fabric.

Water consumption is minimal because we clean the screens with absorbent cotton, which we reuse countless times.

Tissue Utilization

During the design process, we apply the zero waste philosophy . This means that design and sustainability go hand in hand in our case and we guarantee 99% use of the fabric during the cutting of the patterns, of the different garments, bags and each of the elements that we create.

The remaining 1% is reused .

And how? Well, to guarantee the circularity of our economy, the so-called remnants or leftover fabric (which is usually so small that little can be done with it) we send it back to the factory so that it is shredded, returned to being thread and fabric, or we convert it in creation pieces for new projects, prototypes or proposals.

Raw Material and Packaging Rewinder

All the materials we use are recyclable and/or biodegradable , both when we talk about the final product and when it comes to the packaging process.

For example, our masks are made of organic cotton, which means that they are biodegradable and decompose naturally if they have not been taken to a container where the fabric can be recycled.

Another example that we are proud of is the ear savers or ear protectors that we have designed and that are made of papier-mâché, a material made in Spain, from sustainable mineral sources (no trees) and that replaces similar products that exist on the market and that are made of plastic (harmful to our environment, non-biodegradable) .

Regarding our packaging, in the case of the masks, for their protection and to guarantee that they reach you in perfect condition, they are protected in a recycled and recyclable plastic bag, which, in addition, can help you keep your mask isolated, a time you use it and it is washed again.

In the rest of our products, our packaging is based on natural jute cord, totally reusable and biodegradable, and different weights of cardboard and paper , always FSC .
