MecArmy SGN7 mystery accessory

I purchased a couple of these MecArmy SGN7`s.
1 x Pink and 1 x Black .

I made 2 purchases of the same 1 x Pink 1 x black SGN7

BOTH times they came with the same extras.

The black came with lanyard , instructions and key chain rings ,
But the pink came with the same extras but had 2x rubber rings as well.
1 x yellow 1 x black.

BOTH times the pink had the extra rubber rings and the black one did not.

I have no idea what they are for,
They do not really fit on the flashlight neatly anywhere.
Can anybody please tell me what these rubber rings are for and do they only come with the ` pink ` version or has the seller placed these things in the one box by mistake ,` Twice ` .

Thank you Mick.
