All customers who place an order on Shopkablo.com after February 22nd, 2020 will receive a 2nd generation Kablo bottle. If you found our product on Amazon, you can distinguish between the older generation and newer generation by looking for "1st Generation" and "2nd Generation" in the Amazon product titles.Our 2nd generation Kablo bottles come with a solid (one-piece) 304 stainless steel cap, making them virtually indestructible, corrosion-resistant, and 100% dishwasher safe. This means you will not get any of the toxic glues that 99% of water bottle manufacturers use in their caps. Industrial adhesives used in caps will often break down, off-gassing harmful chemicals that we inevitably ingest. Our one-piece solid stainless steel cap ensures the Kablo quality and safety you have grown to love, and that we stand behind. You will also notice that our bottle, branding, and packaging have seen some updates.
