This is Standley
The only click-on guitar foot
Standley's guitar foot attaches easily and non-permanently to your acoustic guitar's strap button and allows your guitar to stand upright on its own. Standley is ideal for living room/bedroom guitars. The product has a universal fit, weighs just 140 g (5 oz) and is the first guitar stand to fit into any guitar case. In stores now.
