Con-Tact Square Glass with Locking Lid - 3.4c

The Con-Tact brand Square Glass Container with Locking Lid marked "-3.4c" represents the mid-sized 3.4-cup capacity variation, which holds exactly 27.1 fluid ounces (approx. 800 milliliters). This square design maximizes shelf space and is widely used for single-serving dinner leftovers, fresh produce storage, and multi-day meal prepping.

• The thermal-resistant borosilicate glass base safely transitions from cold storage to high heat. You must unlatch and remove the plastic locking lid before using an oven or microwave to safeguard the airtight silicone ring from heat deformation.
• Fully freezer-safe for preserving ingredients or batch meals. Leave roughly a half-inch of headspace if freezing liquids to allow for natural volume expansion.
• The glass base is safe for any dishwasher rack. To maintain the secure snap-fit of the locking latches, place the plastic lid on the top rack only or wash it by hand.
