Exactly what you expect from a small storage tub. Enough capacity for 50g of powder. They are a stack system but would have been better to have 3 lids as well for packing them in the gym bag. 

Help friend to buy and he said it’s good for protein powder storage for gym. The size design just fit. 

purchased Second time, good to use and is cheap.

Wonderful and handy for storage, especially when I need to consume straight after workouts. However, it would be great if a 'spout' of some sort could be incorporated into the next design. Otherwise, tipping the powder out into my water bottle can be a messy affair. I resort to using a piece of paper to form a 'funnel'

Great for supplements all in , going to get another set on next order 

Does what it’s made for. Used it countless times with protein, bcaa, creatine etc. Screws on well so no powder spills. And stacks conveniently so you can split a days worth of shakes in one stack and just take from the top etc

Great produce just the right size to add meal replacement or protein powder ! Great for travel purposes and not have to take big containers or already mixed shakers. Love it 

Really simple product that is surprisingly convenient when you're constantly on the move to store your protein powder, creatine, vitamins, etc. Super useful to prepare your dose before the gym so you don't have to make the protein shake at home for instance, or pour the powder in the shaker before, which we all know will inevitably lead to clumps. This way you can be away, add the water first, the powder, and then not face the annoyance of shaking vigorously multiple times to get rid of some bits of powder that stick to the edges.

Wasn’t sure on the size these boxes were going to be when I arrived however they are spot-on the right size that I need to put any supplements when I go away for a least a week very easy to use and keep things airtight and like I say I went away for a week and managed to get each scoop times seven of the products I needed in these fantastic

Super little pots to carry Protein Powder or supplements...just the right size to hold a scoop.  Sturdy & screw worthy, these didn't disappoint, so glad they came back in stock.
