17mm plastic base, metal cap Tack Button

This easy to attach aged brass (brownish colour) plastic base, metal cap tack button measures 17mm in diameter. Strong and easy to apply by pushing a ‘tack’ into the barrel cavity with a small press. Careful use of hammer is also possible for sampling.

Generally, a solid aluminium tack (rivet-like pointy companion) with a barbed tip will give a fantastic closure and very long and reliable service.

Can’t really go wrong. Idiot-proof.
