This is a hose holder for diving. It's for temporarily securing the hoses for your gauge and octopus. It's an item that lets you quickly attach and detach used hoses and high-pressure hoses. It's a diver's golden rule to prevent your gauge and octopus from dangling in front of your BC while you're engrossed in underwater photography, unknowingly damaging coral. This is a 500-yen investment to prevent that. Considering the unit price and shipping costs, the profit margin is minuscule, so you, being a kind person, wouldn't ask for a discount, would you?
