PAXCOO100 Pcs Metal Swivel Lanyard Snap Hook with Key Rings (Silver)

Are these clips strong enough to hold 2.5 pounds?

Can you use these split rings for dog tags..are they strong for big dogs??

I would like to know if you think i could use this on a bracelet to pucnh a hole in my room card on a cruise??

I need to put a tassel on the ring im wondering if the hole of the tassel will go through?
