Your container/water bottle is not broken! The friction and clanking sound is a natural occurrence when metals are not coated with lubricants or forever chemicals to help them glide smoothly. Staying true to our mission to create non-toxic products, we chose to use raw, high quality stainless steel for all of our lids and vessels. No artificial coatings have been added. Over time and with regular use and cleaning, the sound will dissipate and your containers will open and close more smoothly.
