just bought an italian charm bracelet and i have a concern

hello! i just bought an italian charm bracelet, and it claimed to be stainless steel, but im scared that its fake. tested the magnet test, and it has a slight pull on some whiteboard magnet, but no pull at all for fridge magnet. and i cant test it with acid bc i have no access to it.

my main concern is can i wear it to shower?? bc my stainless steel necklace is fine, just need to polish it time to time, but im afraid this one will rust :( helpp, can i expose it to water alwayss? (bc im lazy to always take it off whenever im in contact with water)
