Wren paper products are coated with Nano liquid glass, making them water, dirt and oil
resistant. Unlike with fabric that dirt can cling to fibres, paper is smooth and dirt does not
naturally cling to it. However, if your sleeve does get some marks on it over time, gently use an
eraser. Be careful of rubbing too hard as this may remove some parts of the Nano protective
If you get an oily mark on the paper that the Nano was unable to resist, try putting some bi-carb or baby powder on the mark overnight. The powder will “absorb” the mark and make it
Lastly, if the mark stubbornly refuses to budge, we suggest taking a permanent marker to it and
making it a unique characteristic of the sleeve.
Cleaning your face mask
The face masks are coated with a second Nano that has anti-microbial qualities. You need not wash this surface but, if you would like to, no harm can or will be caused.
Use an alcohol swab, or a soapy damp cloth to wipe the paper surface clean. The surface is also
water-resistant, so no harm will be caused.
No. Not unless you cut it! It is, after all, a paper product and you need to treat it as such! But
paper is also an amazing material with incredible strength — one that we take for granted. It is made from a tree after all!
No. Most laptops are made with solid state hard drives that are not affected by magnetic forces. The magnets used in the wallets are strategically placed to limit interaction with any magnetic
strip on any card.
Our paper surfaces are coated with a super fine layer of Nano Liquid Glass. This makes the surface water resistant.
If water gets on the paper or you find yourself dashing between buildings and using your laptop as an umbrella (which we do not recommend), simply wipe the excess water off it as quickly as possible. Your laptop sleeve should look good as new!Our Guarentee Watch water resistancy video
