Lights are usually turned on with small on/off switches or front-barrel switches. Some keychain figures require pressing and holding a chest or body button to light parts like the feet.
You can find single pens and multi-packs; listings specifically include single-item packs and 2‑pack pen sets.
Features include protective plastic end caps that help preserve ink, ergonomic comfort grips for easier writing, and anti-roll designs to keep the pen stable on flat surfaces.
Some listings note pens are made without PVC and that packaging is FSC certified.
Both types are offered: gel ink pens with fine 0.07 mm points and 1.0 mm ballpoint pens appear across the selection.
