IMPORTANT / NO AIR SHIPPING: We can ship Co2 Cartridges ONLY via land transport. Co2 Cartridges are banned for airline transport or travel. Co2 Cartridges at higher altitudes and pressure can explode. Do not travel on flights with Co2 Cartridges. This may result in loss of valuable time and missed flights too! 🙂 – Travel Advisory Warning from Team @ Cycling Boutique!
Co2 Catridge’s surface becomes extremely cold to freezing temperatures when the Co2 can get pierced. You may use a glove, cloth, or both, etc., to hold the cartridge to prevent your fingers from freezing fast!
