Tired of lugging a giant tub of protein powder to the gym or on trips? This AKIZUKI JOO container set is your perfect on-the-go solution. You get 4 stackable, BPA-free plastic containers that screw together neatly. Three of the layers each hold about 1.8 oz of powder, and the bottom layer holds about 0.7 oz (perfect for pills or smaller servings). You can mix and match – take all four for a big supply, or just take one or two for a short trip. The best part? The top lid has a built-in funnel, so you can pour your powder into a shaker bottle mess-free! It even comes with a carabiner clip so you can attach the whole stack to your gym bag or backpack. The whole thing is compact (about 2.76 x 7.87 inches), lightweight, and dishwasher safe for easy cleaning. It's not just for protein – use it for pre-workout, vitamins, powdered drinks, or even snacks like nuts. Super smart design for anyone with an active lifestyle.
