Thank you for viewing. This is a set of two TSUNAGU connectors from neru design works. *Individual sales are not available. These connectors are used to connect LED lanterns like FUTAMATA and 38灯. The design blends seamlessly when attached to FUTAMATA. Internal packing prevents gas leaks when attached to gas canisters containing gas. Rubber packing is also included on the screw side for attaching LED lanterns, allowing for fine adjustments to the lantern's direction. Of course, it can also be connected directly to a gas canister. Material: Brass Please comment if you have any questions.
