Spells (3e)

This spell allows the character to inscribe the character's personal rune or mark, which can be no taller than 6 inches in height and consist of no more than six characters. The writing can be visible or invisible. An arcane mark spell enables the character to etch the rune upon any substance (even stone or metal) without harm to the material upon which the mark is placed. If an invisible mark is made, a detect magic spell causes it to glow and be visible (though not necessarily understandable). See invisibility, true seeing, a gem of seeing, or a robe of eyes likewise allows their users to see an invisible arcane mark. A read magic spell reveals the words, if any. The mark cannot be dispelled, but it can be removed by the caster or by an erase spell. If cast on a living being, normal wear gradually causes the mark to fade in about a month.

Arcane mark must be cast on an object prior to casting Drawmij's instant summons on the same object (see that spell description for details).
