Planning notes

Match the object and its consumable or format

Gel Ink Ballpoint Cap Type Pen 0.38 mm lists the instrument type named in its title. The record does not name a matching consumable here; obtain the exact model’s refill or filling instructions before buying one.

Use a concrete capacity or fit check

Check the full model and the actual nib, tip or lead option separately from body colour. For a daily-carry choice, check the capped or closed instrument with the actual pocket or case and retain its refill designation with the purchase record. A shared brand does not confirm interchangeable nib units or an identical refill length.
