Review on 🍶 BlenderBottle ProStak Twist and Lock Storage Jars Expansion 2-Pack with Pill Tray in Clear and Red by Leslie Wallace

Damn! I really wanted to love this product and it was entirely my fault for reading the chart wrong. The BOTTLE of the blender has an airtight seal, but the Prostak Expansion System does not. The snack stack is definitely not airtight as the locking mechanism used to connect the containers is just hard plastic to hard plastic with no rubber airtight seal. I tested it this morning and put it in a plastic bag to see if the pickled cucumber salad I brought to work would leak. Of course there is pickle juice in the bag. Before I went to work I made sure the jar was fully plugged in and it was still leaking. However, the containers are the perfect size for protein powder, some chia seeds, nuts, and a small amount of carrots. It's perfect for dry or mostly dry snacks, and the containers are the perfect size for the portion control that I strive for. I would give these 5 stars if they would only make these nifty little containers airtight!
