UPTRUST Stainless Steel Kids Bento Box 3-Compartment 40oz (1200ml) — Locking Lid & Removable Silicone Seal

This UPTRUST 3-compartment stainless steel bento box holds 40 oz (1200 ml) and is made from 18/8 (304) food-grade stainless steel for long-lasting, safe food storage. Designed for school days, picnics, or travel, the box combines sturdy metal construction with a lockable lid and a removable silicone seal to reduce spills while offering three practical meal sections.

How does the lid prevent leaks and accidental openings?

The lid uses a locking clip and a detachable silicone seal ring to form a dependable closure that resists accidental opening when tossed into a backpack. While the seal and clip work together to keep the lid shut and minimize leaks, the internal dividers are not individually sealed—so wet and saucy items should be avoided between compartments.

• Locking clip secures the lid during transport.
• Removable silicone ring for improved sealing and easy cleaning.
• Note: compartments are not watertight — pack primarily dry or separately sealed wet items.

What materials and care instructions should I know about?

The lunch box is crafted from premium 18/8 (304) stainless steel, a corrosion-resistant, food-safe alloy that won’t retain odors or stains. Both the box and its lid are dishwasher-safe for quick cleanup; the silicone seal can be stretched and reinserted if it becomes loose.

• Food-grade 18/8 (304) stainless steel body — durable and odor-resistant.
• Dishwasher-safe for convenient maintenance; hand wash recommended if you want to preserve the finish.
• Silicone seal removable and simple to reinstall after cleaning.

How much fits inside and what meals work best?

This bento measures 7.3 x 5.4 x 2.3 inches and holds about 40 oz (1200 ml), providing three compartments sized for a main, a side, and a snack. It's ideal for sandwiches, wraps, salads, fruit, chopped vegetables, and dry snacks—portion-friendly and great for balanced kids’ lunches.

• Total capacity: 40 oz (1200 ml) across three sections for portion control.
• Dimensions: 7.3 x 5.4 x 2.3 inches — fits most backpacks and lunchboxes.
• Recommended for dry or separately sealed wet foods due to non-watertight inner dividers.

Is the bento suitable for daily school use and travel?

Yes—its compact footprint, sturdy stainless-steel build, and locking lid make it practical for everyday school lunches and light travel. The locking clip reduces the chance of the lid popping open during commutes, while dishwasher compatibility keeps cleaning simple for busy families.

• Compact shape fits standard lunch bags and backpacks.
• Sturdy construction stands up to daily use by children.
• Easy to clean for quick turnaround between uses.

Who is this for: Families and caregivers seeking a reusable, durable lunch solution for kids who need portioned meals and reliable closure. It’s especially useful for parents who want a metal alternative to plastic, value dishwasher-safe convenience, and pack mainly dry or pre-sealed wet foods for school, picnics, or short trips.
