All about magnetic glasses

Material of silwy® crystal glasses and porcelain cups

We source our crystal glasses and porcelain cups from the SCHOTT brand in ZWIESEL. The production is based on Tritan composite, which is considered one of the most resistant materials in terms of real glass.

The stem of my crystal glass is broken off

This happens in only extremely rare cases. Please feel free to contact us (info@silwy.de), because the reorder of a single replacement glass is possible. 

Glue residue in the form of drops on my crystal glass

You can try using a cutter knife to carefully scrape off the drops. Don't worry, the crystal glass won't get scratched! If it still doesn't work, please contact us.

My magnetic glass was damaged during transport

Of course we will send you a new glass in such cases. Contact us by mail (info@silwy.de) and please attach pictures of the defective glass. We will do the rest for you.

My plastic glasses longdrink have bulges inside

This is not a production defect. The bulges have the purpose of making the glasses stackable.

Can I stack my colorful drinking cups triple too?

No, we do not recommend this. Stacking can cause edges to appear on the cups.

Can I put my magnetic glasses in the dishwasher?

We recommend washing by hand, as the high temperature fluctuations damage the magnets.

All about accessories

What do I have to consider when attaching my metal strip?

You should follow the following steps:

The surface should be smooth and cleaned with spritus beforehand.
Peel off the 3M adhesive tape from the strip - press the strip firmly into the desired position.
Wait for about 30 minutes after applying the strip, then load it. 

Which item can I use to store my glasses upside down?

You absolutely need our metal strip for this. The metal-nano-gel-pads that are included in all of our glass sets are not suitable for this.

Does permanent wetness / humidity damage my pads?

Yes, as this can cause the metal-nano-gel pads to start rusting. We therefore do not recommend it.

Does heat harm my metal-nano-gel-pads?


Direkte (und dauerhafte) Sonneneinstrahlung ist für unsere Pads nicht empfehlenswert. Nach Möglichkeit sollten auch starke Temperaturschwankungen vermieden werden.
Unser Tipp: Nach Verwendung die Pads abziehen, an einer Klarsichtfolie anbringen und bis zum nächsten Gebrauch im Schrank verstauen.

Surfaces on which the metal-nano-gel-pads should not be applied

 tables should be avoided at all costs. Oiled and uneven surfaces are also not recommended. 

Surfaces to which metal-nano-gel-pads can be applied

All surfaces that are smooth / sealed / flat.

All about hooks & pins

I have the feeling the holding power of my pad is weakening

This "problem" can be solved quite easily:
Clean the pad under clear water and let it dry for 10 minutes. After that, the sticking power is restored and the pad is like new. 

What is the difference between the hooks and the pins?

We offer different hooks and pins for different areas of application. You can find the exact information about their adhesive force and areas of application on the respective product page.

Surfaces to which metal-nano-gel-pads can be applied

All surfaces that are smooth / sealed / flat.

I dropped my hook and broke it - and now?

Unfortunately, it is nothing new that magnets can break on impact. You are welcome to get supplies in the store. We also offer our hooks without a pad.  

Step by step instructions for correct attachment

First clean the surface with methylated spirits or other alcohol-based agents.
Once the surface is dry, first apply the pad and a few minutes later the hook / pin.
The full sticking power unfolds within 10 minutes.
