JoyJolt Borosilicate Glass Food Storage Set 24pc (12 Airtight Containers) – Stackable, Oven & Freezer Safe

These are 12 pairs (24 pieces) of JoyJolt fluted borosilicate glass food storage containers with airtight, hinged lids designed for meal prep, fridge/freezer storage, reheating, and leakproof transport.

JoyJolt’s 24-piece glass storage collection combines durable borosilicate glass with removable silicone seals and secure hinge clips, giving you a complete selection of rectangle, square, and round containers in multiple capacities. The set is designed to stack neatly, resist thermal shock, and move easily between freezer, oven, microwave, and dishwasher (lids handwash recommended). Ideal for anyone who wants a long-lasting alternative to plastic Tupperware, the set organizes pantry staples, leftovers, and weekly meal prep with clarity and confidence.

How does this set handle temperature changes and reheating?

The containers are made from borosilicate glass, a material known for high thermal resistance that tolerates rapid temperature shifts better than ordinary glass. You can safely move filled containers from the freezer to oven or microwave for reheating; however, lids should be removed before oven use and are handwash only. These properties make them practical for batch cooking and thaw-and-reheat meal routines.

• Borosilicate glass resists thermal shock for freezer-to-oven use (remove lids for oven).
• Microwave-safe for reheating; lids vented or removed first.
• Dishwasher-safe glass pieces; lids recommended to handwash only.

Are these containers truly airtight and leakproof for lunches?

Each container uses a removable silicone seal plus locking hinge clips to form an airtight closure that reduces odors and keeps food fresher. Because the seal and clips lock tight, the set works well for transporting soups, sauces, or layered meals—just ensure clips are fastened correctly. For long liquid transport, double-check the silicone gasket sits evenly in the lid before sealing.

• Removable silicone seal creates an airtight environment to extend freshness.
• Secure hinge clips lock down lids for leak-resistant transport.
• Best practice: inspect and clean gaskets regularly for consistent performance.

What sizes and shapes are included, and how do they fit everyday needs?

The 24-piece set includes 12 glass containers in rectangle, square, and round shapes, with two matching airtight lids per container. Capacities range from compact 11–13.5 oz sizes up to larger 35 oz rectangles, covering single-portion lunches, snacks, salads, and family-size leftovers. The fluted design stacks stably and shows contents clearly, making pantry organization and portioning straightforward.

• Rectangle sizes: 35 oz, 21 oz, 12 oz (two sizes noted for versatility).
• Square sizes: 27 oz, 17.5 oz, 11 oz (two compact squares ideal for sides/snacks).
• Round sizes: 32 oz, 21 oz, 13.5 oz (two mid and small rounds for soups and salads).

How do I care for the lids and glass to keep them performing well?

Glass pieces are dishwasher-safe; lids are best cleaned by hand to preserve the silicone seal and hinge clips. Remove silicone gaskets occasionally to rinse and air-dry fully to prevent trapped moisture or odors. Keep clips free of sticky residues and store lids slightly open if long-term sealed storage is not needed.

• Wash glass in dishwasher; handwash lids and remove gaskets to dry.
• Inspect and reseat silicone seals after cleaning to maintain airtightness.
• Avoid sudden extreme temperature shifts when lids are closed to protect seal life.
