GoStak Twist n' Lock Storage Jars, 40cc 4-Pak, Black

I bought two sets (3 in each) of these in the 100cc size. Each container perfectly fits one scoop of my protein powder. It was a little messy to transfer the powder from the scoop to the container, even with a funnel. So, I found that just using the container to scoop out the powder works best. The lids seal tightly enough that you can just rinse and wipe the container after you fill it without having to worry about water intruding when you rinse. I just traveled using these and it was great. All six of my containers nicely attached to each other and it was very easy to just pack the cylinder in my suitcase. They never leaked, came apart, or broke; it worked perfectly. This is a nice travel solution for packing the protein that worked quite well for me. I am very pleased with this purchase and highly recommend.

These are great quality and fit in the Dometic fridge door. They’re leak proof and the hard foodsafe plastic doesn’t absorb odors. I use them to keep condiments in the van without using too much space.

I purchased the BlenderBottle GoStak Twist n’ Lock Storage Jars (150cc, 2-Pack) to help me stay prepared while trying to be healthy on the go, and they’re a great addition to my routine. They’re the perfect size for pre-measured protein powder, supplements, or snacks. I love the twist-and-lock design, which keeps everything secure and mess free in my bag. I love the fact it’s black, which makes it simple and match with just about anything. They’re lightweight, durable, and super convenient especially when I want to prep two extra protein shakes ahead of time. Overall, this is a great, practical product for anyone focused on fitness or healthy habits. Simple, effective, and definitely worth it!

These cute containers are convenient for on the go snack. Fits perfectly into any bag. In the pictures provided, I have salad dressing & powder nutrients for my shakes. Fits into any business lifestyle & great for meal prep. The twist & lock system is great for stacking. This product is also leak proof. Dishwasher safe.

They appear to be pretty sturdy. Ended up grabbing these after I lost a set from another brand. These ones are nice because they are very small, which makes it easy to find different storing locations within a backpack or bag. At first I was worried my entire protein scoop wouldn’t fit, but as long as you scoop your protein in carefully, it seems to manage fine. Haven’t had any spills yet.

These are great for protein powder when going to the gym. Great quality, compact in size, and durable. Thick plastic that you don't have to worry about breaking when it gets dropped. Holds the exact portions of what you need.

I was initially going to just write a review to the effect that it does what it’s supposed to do, but that would be short-selling this product… There are likely less expensive ways to store stacks of powders. What’s really amazing is how well the containers stay shut — and how they somehow can be unscrewed, regardless of how tightly they are closed, when they’re hooked onto the container above. I travel a lot and have had more spilled powders than I can count - so I am grateful to have found something that actually stays closed even when bounced around in my bags. My only criticism is that there are only a few sizes available as add-ons and – but it’s worked fine for my needs.

These are great! No leaks and seals tight to keep my food fresh! They are so easy to clean and easy to use, and the small size is great for travel, especially light travel.
