Belay Device Carabiner 8-Piece Set PETZL Black Diamond

This is a set of belay devices and carabiners.
I purchased it used but am selling it as I haven't used it.

Product Details:
① PETZL GRIGRI - 1 piece
② PETZL Carabiner PREINO - 1 piece
③ Black Diamond Carabiner (Purple) - 2 pieces
④ Black Diamond Carabiner (Gold) - 1 piece
⑤ Black Diamond Carabiner (Light Purple) - 1 piece

I don't have much knowledge about mountaineering or climbing, but I will answer questions to the best of my ability.

The items have many scratches overall, but they should be fine for use.
The Grigri has some rust as shown in the image.
We recommend this product to those who have knowledge and can maintain it themselves.

Thank you for your understanding that this is a used item before purchasing.
