Flavor Cartridge Holder | Fits 2 Cartridges | Compatible With Cirkul Sips | Keep Fresh For Up To 10 Days | BPA Free Plastic

I like to have a sip with caffein when I wake, and then regular sips throughout the day, so that when it is time for bed, I am not too wired from the caffein. The problem with sips is that it retains the water, and therefore, when removed from the bottle, the sip can leak water. Therefore, storing it in the box in which it came is not a great option. With this product, you screw the sip onto the holder, and since it screws in and is a tight fit, it won't leak water everywhere. This means you can change your sip flavor without worry. Definitely something anyone who uses Cirkul should have! Word of advice, however, this device does not preserve sips. No device does this. Cirkul suggests throwing out sips that have been put into water 10 days after it was introduced to water. So using this device, that rule still applies. This device is just so you can safely store your sips if you want a new flavor.

Works perfectly for what its intended for.

I wanted to have storage for my cartridges that I open. When getting this holder, I was surprised on how durable the plastic was. It is made with a thicker material and has two slots. It does what it needs to do, which is storing your cartridges safely. All you do is drop your cartridge in, screw it in and then you’re done. This cartridge holder solves the problem of not having storage and allows more flexibility with switching out flavors. You can also tip this over and the cartridges don’t fall out. It’s a great option.

Works great for cirkul flavors. I like that it’s two separate compartments so if you don’t use one side it stays clean. I also got the plain caps for the cirkul bottles when I want to use as a plain water bottle and they work on this too so you can close one side if you don’t use it

Does exactly what I wanted it to do, which was hold Cirkul cartridges. Took off 1 star because I think the price is a little steep for what it is.

Holds your flavor cartridges and allows you to switch them out whenever you want. Nice thick plastic keeps your favorite flavors handy. The cartridges screw in securely for a good fit.

Yes, this was a frivolous purchase. Is it really that serious? Actually, yes. The average person probably doesn't need this, however, for my situation it's priceless. It is so much more convenient to fit in my driving bag. It also remedies that annoying leak when replacing. I like the space saving design and that it keeps them clean until ready to use.

This little device does keep the Cirkul cartridges fresh, clean, ready for use when you want. It's nice to be able to switch cartridge flavors without having to use the entire cartridge and have a place to store them, especially as they are supposed to be refrigerated. The holder is also good as I found that the stored cartridges leak water.
