Harry Potter metal keychain time reverser

Keychain Harry Potter

Officially licensed Harry Potter keychain made of metal. The size of the pendant is about 4 cm.

A time reverser (in the original: time-turner) is a small silver hourglass on a long necklace. Each revolution of this powerful magic glass turns back the time by one hour for those who wear the chain around their neck. In this way, you can experience the time you have already experienced a second time, and in this way use it twice, or subsequently add something to what has already happened.
However, such time travel is very dangerous, because time travelers are not allowed to change what they have already experienced. You can only insert something that goes with it. They must also not be seen by anyone – not even themselves – because their double appearance would normally have more or less drastic consequences.

Hermione Granger had been given a time reverser at the beginning of her third year at Hogwarts, with special ministerial permission, so that she could manage her overload of chosen school subjects in time. She also complied with the ministry’s directive to use it only to manage her overflowing schedule. Besides, she kept her silence and didn’t reveal anything about it, although her friends often asked her about her incredible time management.
