They typically have plastic barrels and novelty toppers such as soft, squeezable snowman toppers or snow‑globe–style toppers filled with faux "snow."
Color switching is mechanical: you push or toggle parts of the topper (for example, the snowman’s hat or snowflake) to select black or blue; some designs use left/right antlers to switch colors.
Common types include candy‑cane striped plastic novelty pens, soft squishy‑topped pens, shakeable snow‑globe toppers with faux snow, and retractable dual‑ink snowman or reindeer pens.
Ink options shown include Black, Multicolored, and dual‑color pens that write black and blue. Listed point sizes include 1.0 mm and 2.05 mm.
