Shadow Overflow Question

Found these two pieces taped to the inside of the overflow but I don't see any mention of them on the box. Any idea what they are? The pics are of the front & back. They are probably an inch by a half inch.

They help you open the slotted cover. If you put them into the grove at the end and twist slightly the slotted front cover will come right off. Senergy Reef talks about them in one of their videos. I never use them cover comes off easily for me.

Thanks! I thought that's what they might be for but wanted to double check!
