GoTubb One-Handed Open & Close Containers
It's not sleight of hand but squeeze of hand that in one quick motion opens or closes a GoTubb container. The hard cylinders' - you know I have to say it - handy design allows you to access pills, snacks, small pieces of hardware, office supplies, and any other little knick-knacks one-handed, without twisting, flipping, or fumbling to get inside.
Maker humangear describes GoTubb as "the civilized, one-handed container," with a lid that opens when you squeeze its sides, and presses back on top of the base to close. The lid is transparent to show what's inside, plus has a recessed, textured labeling area. Available in various colors and sizes, GoTubbs are food-safe and BPA, PC, and phthalate-free.
