Magic Mill Borosilicate Glass Storage Set, 12 Dishes with 12 Snap-Lock Lids in Round, Square and Rectangular Shapes

A borosilicate glass set built for cooking ahead: twelve dishes across three footprints, each with a matching snap-down lid whose silicone gasket seals against spills inside a bag. The glass suits an oven, a microwave and a freezer alike, so a portion travels from cold storage to the table without changing vessels.

• Piece count: twelve dishes plus twelve lids, twenty-four items altogether.
• Shapes and volumes quoted by the maker: rectangles at 35, 21.5 and 12 ounces; squares at 27, 17.5 and 11 ounces; rounds at 32, 21 and 13.5 ounces. Dish heights fall between 1.75 and 2.3 inches.
• Sealing: locking tabs pull each lid down onto a silicone gasket, holding soups and sauces without seepage.
• Glass: borosilicate, stated as oven-worthy to 752 degrees Fahrenheit, which is 400 Celsius.
• Lids: plastic with silicone sealing, catalogued in black.

Heat and cleaning limits: lids must come off before anything goes into an oven or under a grill, since only the glass is rated for those temperatures. Dishes are marked dishwasher safe; wash lids and gaskets by hand so the seals keep their shape, and let glass reach room temperature before it meets a hot oven or cold water.

Two gaps in the supplier data: the capacity field reads 12 ounces, which is the smallest dish rather than anything about the set, and the recorded 16 x 12 x 7 inches describes the packed carton, not any single dish. The nine volumes listed above also fall short of the twelve dishes in the box, so some sizes must repeat.
