**IMPORTANT NOTICE: The 421 CUBS are in extremely high demand. We work hard to keep them in stock, but they may sell out quickly. Due to this popularity, there is often a waitlist for CUB cylinders. Please be aware that these items are considered special order and may take time to manufacture and plate. Feel free to contact us for updates on your cylinder's progress, and we will always be honest about its status. Keep this in mind when making your purchase. Thank you for your understanding.
