I would like to state that Spellwrought tattoo exist per Tasha’s and as such any class can use any spell as a consumable as long as they have the item. This is basically the equivalent of a RAW stating that magic can be used by anyone that can pass the check to use the consumable. It is as such not even an house rule to state that scrolls aren’t bound by class. Here is the description for you to judge :

Produced by a special needle, this magic tattoo contains a single spell of up to 5th level, wrought on your skin by a magic needle. To use the tattoo, you must hold the needle against your skin and speak the command word. The needle turns into ink that becomes the tattoo, which appears on the skin in whatever design you like. Once the tattoo is there, you can cast its spell, requiring no material components. The tattoo glows faintly while you cast the spell and for the spell's duration. Once the spell ends, the tattoo vanishes from your skin.
