Guitar wall hangers: a 4-pack for $7

We used to have a lot of guitars, ukuleles, and cigar box guitars leaning against walls, stacked in closets, and hiding under beds. I bought this four-pack of guitar hanger hooks for $8 in January, now they are priced at $7 for four (You can also buy two for $6 or six for $9). They come with wall mounting hardware. They're highly rated on Amazon.
