A small thing that solves two real problems. A brass burner packed in direct contact with aluminum pans invites galvanic corrosion; and a burner with any fuel left in it can weep into the cookware and leave everything tasting bitter. The bag stops both. The burner instructions are printed on it.

Two per pack — Trangia sell this as a 2-pack, and the distributor lists it as “packaging only,” which undersells it.

Specifications

• Quantity 2 per pack
• Weight 10 g
• For the Trangia spirit burner (article 602500)
• Material and dimensions — not published

Worth knowing before you buy: Trangia say this bag is already included with complete stove sets and with separately-bought spirit burners. So this is the replacement pack, not something a new stove is missing.

Made in Sweden, at Trangia’s factory in Trångsviken.
