A couple of posts ago, I asked if anyone else had noticed that Klean Kanteen had switched from stainless steel (with a little bit of plastic) caps to all polypropylene (fancy plastic) caps...although no one responded in the affirmative at that time, I e-mailed the company to inquire about it.
Guess what? I wasn't crazy nor was I making up stories...it's true. I received a reply from the company today. Here it is:
Thank You for your email and your support of Klean Kanteen!
This all polypropylene cap change was made on Jan. 1st for 3 different reasons:
1) The continual rising costs of stainless steel, and our desire to keep our bottle prices at the current price levels. This change keeps our cap prices down and allows us to do this.
2) The stainless on stainless threading of our bottles and caps. Many customers have voiced concern that over time small amounts of stainless residue are getting into their drinks from the screwing and unscrewing of these caps.
3) The noise that is made from the screwing and unscrewing of the stainless caps. This is not a big concern of ours, but customers do complain about it.
If you have any further questions please contact me via the info below.
One planet, one you!
So...in pondering point #2 from the letter above...has anyone else encountered this? Does anyone have knowledge of stainless steel that could address this theory? I had already guessed prior to receiving the response that financial reasons were coming into play here... The noise of the lid never really bothered me... But I find the whole "small amounts of stainless steel residue" to be very curious...
