General:
I wanted to buy cleaning cloths for my glasses so that I don't always have to use these disposable wet wipes.
I also wanted to be able to clean smartphones with the wipes.

Packaging:
Small simple packaging. All wipes were each in an individual plastic wrap. There's definitely no other way. I would be happy if we could avoid something like this in the future.

Quality / workmanship:
Good workmanship and also good quality. You don't feel as thin or as frayed or anything like that. They're not too big either.

Use/Application:
Simply rub dry over your cell phone or glasses and the stains will go away. No need to moisten or anything like that.
This is always enough for simple fingerprints.

Price/performance:
Absolutely top for the price of around €10!
€1 per cloth. Others are even more expensive here.

Tips/Notes:
Do not throw away plastic wrap and use it for storage as long as possible. I put it in all my bags and jackets so I have a cloth ready everywhere.

Conclusion:
I can recommend it to anyone who wants good, cheap glasses or cell phone cleaning cloths. Just don't expect miracles.
