# Pen Refills

Recipe files go in `data/<namespace>/recipe/`, with `"type": "isekubed:pen_refill"`.

## Fields

| Field | Always present | Description |
|---|---|---|
| `type` | yes | Always `isekubed:pen_refill`. |
| `category` | yes | Crafting book category string (`building`, `redstone`, `equipment` or `misc`). A crafting-grid recipe: a damaged magic pen plus one ink restores ink. The amounts are fixed in code, not in the recipe. |

## Example

From the mod: `data/isekubed/recipe/magic_pen_refill.json`.

```json
{
  "type": "isekubed:pen_refill",
  "category": "misc"
}
```
