VartieyFlavors Cartridges Holder | Compatible with Popular Water Bottles | Single Design | For Flavor Replacement Storage (2-Pack(Blue+Magenta))

These are perfect for carrying around "extra" flavor cartridges. I typically don't swap out cartridges mid use, but I have been caught, more than once, with an empty cartridge. This solves the issue since I can now carry an extra cartridge just in case.

Love these. The cartridges actually screw into them.

love it, its simple but works. i havent had any leaks with it and it does what it says. great for taking an extra flavor on the go or keeping a flavor safe at home.

This product is excellent and perfect for those Cirkul cartridges that aren’t fully spent but you just need a new a flavor! Got a two pack one for each kiddo.

I requested these because my daughter and I drink the flavored water. I have times where I cannot drink the same flavor all day until it's empty, so I like to switch flavors. I usually drop the sip into a coffee cup so it can drain and dry until I am ready for that flavor, again (within the 10 days, of course). This thing little sip holder is cool. The sip screws into the holder so it doesn't fall out and the clip holds it to whatever you want to clip it to. You do have to shake off any excess water before putting the sip into the holder because there are no holes to drain water, but that usually isn't a big deal. I clipped the holder onto my daily bag so I have access to it without having to dig around. You could also put a new sip in the holder when your current sip is getting low. This is a cool little sip holder. I like it.
