BlenderBottle ProStak Twist n' Lock Storage Jars Expansion 2-Pak with Pill Tray, All Black

The 250 ml size is the PERFECT size for TWO scoops of whey protein.I used to put one scoop into two separate 150 ml size ones. That worked fine.But then I accidentally left them at the gym. Obviously gym bros took that instantly.Bought these as a replacement hoping two scoops would fit into one and it does.Pro Stak system is great. I had the other ones for probably a decade and never had an issue with them. They’re still made exactly the same.

Coolest gym powder storer with the hidden compartment in it too makes it perfect to sneak your roids to the gym with your creatine and protein

I use this for whenever I go to the gym. It’s nice that the they stack so you don’t have containers rolling around in your gym bag. I’m able to store all my supplements for the day!

Great build quality, convenient form factor, and versatile. Fits about 100g protein or meal replacement powder comfortably (you could probably squeeze in an extra 20g or so). Perfect for my use case of portioning Huel servings to use on the go. The containers are the perfect diameter to simply dump the contents into a blender bottle to prep. I don’t use the small pill container portion, but it’s a nice feature if you want somewhere to store something small like pills, vitamins, etc.

Love WhiskWare and ProStak products. Perfect for packing snacks in my car or messenger bag. Added the 2 pack to my supply because it was pictured with a pill tray. Product arrived without the tray. Too much of a hassle to return.

I purchased this to replace the plastic bags I would commonly use to transport my protein powder to work, or to the gym, primarily because the plastic bags were unreliable and would often tear open or unseal and make a mess. These storage jars work very well and seal very tightly; I have not experienced any leaks or unintentional openings. Additionally, some plastic scoops or containers are affected by static and sometimes cause powder to 'spray' out when pouring between two plastic containers. However, I'm happy to say these storage jars do not appear to have that problem. The storage jars are robust, within reason, and I suspect I will not have any problem with them breaking or opening inside my gym bag. The storage jars did not have any unpleasant odor when first unwrapping them, and they seem to be resistant to developing an odor even after longer-term storage of protein powder. Overall, if you're looking for a reliable method of transporting protein, pre/intra/post-workout, or any other powder, I highly recommend this option.

These are durable. They’re dishwasher safe. They don’t hold onto odors and that’s because I left hummus in it over the weekend in the summer. The treads on the container feel sturdy. The color is nice and the design is sleek.

Only ones I could find I could put mass gainer size scoops in and their suggested servings! Easy way to keep all my proteins and shakes organized and with me through out the day!
