The WIRED Reviews Team has been covering Amazon’s Big Spring Sale since it began at on Wednesday, and the overall deals have been … not great, honestly. So far, we’ve found decent markdowns on vacuums, smart bird feeders, and even an air fryer we love, but I just saw that Cadence Capsules, those colorful magnetic containers you may have seen on your social media pages, are 20 percent off. (For reference, the last time I saw them on sale, they were a measly 9 percent off.)

If you’re not familiar, they allow you to decant your full-sized personal care products you use at home—from shampoo and sunscreen to serums and pills—into a labeled, modular system of hexagonal containers that are leak-proof, dishwasher safe, and stick together magnetically in your bag or on a countertop. No more jumbled, travel-sized toiletries and leaky, mismatched bottles and tubes.

Cadence Capsules have garnered some grumbling online for being overly heavy or leaking, but I’ve been using them regularly for about a year—I discuss decanting your daily-use products in my guide to How to Pack Your Beauty Routine for Travel—and haven’t experienced any leaks. They do add weight if you’re trying to travel super-light, and because they’re magnetic, they will also stick to other metal items in your toiletry bag, like bobby pins or other hair accessories. This can be annoying, especially if you’re already feeling chaotic or in a hurry.

Otherwise, Capsules are modular, convenient, and make you feel supremely organized—magnetic, interchangeable inserts for the lids come with permanent labels like “shampoo,” “conditioner,” “cleanser,” and “moisturizer.” Maybe you love this; maybe you don’t. But at least if you buy on Amazon, you can choose which label genre you get (Haircare, Bodycare, Skincare, Daily Routine). If this just isn’t your jam, the Cadence website offers a set of seven that allows you to customize the color and lid label of each Capsule, but that set is not currently on sale.
