Travel Starter Kit — 3-Mode Cooler, Gansulin Pen, Cartridges & Case

• 1 × 3-Mode Pen Cooler — USB / power-bank powered, with a freezable ice ring and digital temp display; holds the pen upright and cold, and doubles as the travel case.
• 1 × Gansulin all-metal reusable pen (with zip case) — dials 1 to 60 units in single-unit clicks. No plastic, no disposables.
• 10 × standard 3 ml glass cartridges — a full 10-pack, individually pouch-sealed. Enough for a complete run without reordering mid-way.
• 1 × 30 ml bacteriostatic water (Pfizer Hospira, USP) — the standard diluent for reconstituting research compounds. Multi-dose vial, 28-day use window after first entry.

Bought separately it's about $265 — bundled here at $249, and it ships free.

Pen needles (standard screw-on, not included or sold by us) and your research compound. Everything else is in the kit.

Storage: keep the pen and cartridges dry at room temperature; store the bacteriostatic water at 68–77°F (20–25°C), do not freeze, and discard 28 days after first entry.

What is included in the kit?
A 3-Mode Pen Cooler, a Gansulin all-metal reusable pen (with its zip case), a full 10-pack of standard 3 ml / 300-unit glass cartridges, and a 30 ml multi-dose vial of bacteriostatic water (Pfizer Hospira, USP).

How does the cooler keep things cold?
Three ways: USB or power-bank power, a freezable ice ring for no-power use, and a vacuum-insulated stainless cabin. It holds the pen upright and doubles as the protective travel case.

Do I need to buy anything else?
Pen needles are not included or sold by us; the pen uses a standard screw-on pen-needle interface. You also supply your own research compound.

Is the pen reusable?
Yes. The pen is all-metal and built for repeated bench use; swap in a fresh cartridge as needed.

What is this sold for?
Research, educational, and demonstration use only. Nothing we sell is a medical device or is sold as one, and nothing is for human or veterinary use of any kind.
