2 Pack Keeper Caps for Cirkul - Essential Cirkul Accessories (W+Pink)

This is a great option for drinking water out of your water bottle. You get less air and noise When drinking this way.

This cap cover my Circul bottle flavor holder. I can use my Circul bottle without any flavor. I like having options.

Perfect lid for your cirkul bottle when you have no flavor cartridge inserted. Keeps germs out of an open bottle. Fast shipping from seller.

Exactly what we were looking for! Fit's like a glove on both plastic Cirkul bottles and Stainless steel bottles. Planning on getting a few more soon.

These look like great quality smooth plastic from the images, however they are very obviously printed from a home 3D printer. Some printer plastics are not good safe so there's no way to know if it is. The nature of 3D printing leaves crevices to hold water and mold. The quality is misrepresented in my opinion. Bummer because I wanted a cap option.

I got the 2 Pack Keeper Caps for my Cirkul Water Bottle. They fit perfectly and are essential for keeping the flavors fresh. The white and pink colors look nice. They work well with the Cirkul cartridges. The only problem is that one of the caps was a bit hard to screw on at first. But after a few tries, it worked fine. Overall, they are a good replacement for my Cirkul bottle.

works well with all sizes

Such a great idea , too bad it doesn’t have the sealing power to make this an exceptional product. When tilted, I witnessed leakage from the cap - I tested it a few times , same result. Hopefully they’ll add some type of a seal in the future .
