This viral magnetic travel-toiletry system is rarely on sale, and this discount is legitimately good.

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.
