I have Dino key chains

I got for some reasons 

But now mine 

I put it on my Dino bag

But mom did it

Because I couldn't put at all

(´・ω・｀)

But it's a good one

Because it won't go away or dropped by accident I feel 

Since it is the circle thing 

Iron circle?

I have one more but I will put only one

Because heavy I  think
