S'well 12oz Glass Prep Bowl Set of 4 — Black Tempered Glass, Nesting, Microwave & Oven Safe

The S'well 12oz Glass Prep Bowl Set of 4 are durable, nesting tempered-glass bowls designed for streamlined meal prep and secure storage with pop-top lids.

Whether you batch-cook on Sundays or portion snacks for the workweek, these 12oz bowls combine sturdy tempered glass with a compact nesting profile so you can prep, store, and transport ingredients neatly. Each set includes four oven-safe, microwave-safe, and top-rack dishwasher-safe bowls that tuck into S'well Eats 21.5oz containers for space-saving packing. Built to resist stains, odors, and scratches, the bowls are BPA/BPS-free and made to be reused in place of single-use plastics.

How do these bowls simplify meal prep and packing?

These prep bowls are sized for common portions—grains, chopped veggies, dressings, and snacks—making it easy to portion ingredients ahead of time. Their nesting design keeps counters and lunch bags organized when combined with S'well Eats containers.

• Four 12oz tempered-glass bowls for consistent portioning
• Marked measurements to help portion and follow recipes
• Nests inside 21.5oz S'well Eats bowls to save space
• Pop-top lids keep components separated during transport

Are these bowls oven, microwave, and dishwasher safe?

The S'well 12oz Glass Prep Bowls are made from tempered glass that tolerates daily reheating and cleaning routines. Use them in the microwave and place them on the top rack of the dishwasher; lids are designed for practical leak resistance but should follow care instructions on the label.

• Microwave-safe for reheating foods
• Top-rack dishwasher-safe for easy cleanup
• Tempered glass resists thermal shock better than standard glass
• Follow lid care guidance to maintain seal performance

Will these bowls keep food fresh and avoid messes?

Each bowl comes with a pop-top lid engineered to be leak-resistant for separated ingredients and dressings. The non-porous glass surface resists staining and odors, so leftovers and sauces won’t retain flavors or colors after washing.

• Leak-resistant pop-top lids to contain liquids and dressings
• Non-porous tempered glass prevents staining and odor retention
• Smooth surfaces resist scratches from utensils and scrubbers
• Reusable design helps reduce single-use plastic waste

How do these integrate with other S'well Eats products?

The 12oz bowls are specifically sized to nest into S'well Eats 21.5oz food bowls so you can pack multi-component meals—like a salad with dressing or a grain bowl with toppings—without bulk. This pairing offers a compact, stable system for on-the-go lunches or organized refrigerator storage.

• Designed to nest inside 21.5oz S'well Eats containers for layered meals
• Makes it simple to separate hot and cold elements in one packed bowl
• Compact stacking reduces cabinet and cooler footprint
• Works independently for snacks or ingredient storage as well

Who is this for? The S'well 12oz Glass Prep Bowl Set is ideal for busy commuters, meal-prep enthusiasts, small-household cooks, and anyone aiming to replace disposable containers. If you want a durable, attractive set of glass prep bowls that nest neatly, resist stains and odors, and integrate with S'well Eats for compact meal packing, this set delivers a reusable, space-efficient solution.
