HIGHLIGHTS
HIGHLIGHTS
- 5× Stronger Tempered Glass: Manufactured in Korea with advanced precision tempering, these 400 ml rectangular containers offer five times the durability of regular glass. Their medium capacity design resists chips and cracks caused by everyday bumps, freezer freezes, and microwave reheating, delivering long-lasting reliability for salads, soups, and side dishes.
- 100 % Airtight Silicone Seal: Equipped with a premium silicone gasket, the lids form a perfect airtight seal around the rectangular rim, locking in moisture, flavor, and freshness while preventing leaks. Ideal for storing stews, marinades, and grain bowls, this secure seal ensures your 400 ml portions stay fresh and mess-free during transport or storage.
- Freezer & Microwave Safe: Engineered to withstand temperatures between –20 °C and 120 °C, these containers transition seamlessly from freezer to microwave without warping or cracking. Perfect for batch cooking, you can freeze individual portions and reheat directly in the container, simplifying meal prep and minimizing cleanup.
- Odor & Stain-Resistant Hygiene: The non-porous glass interior prevents absorption of food odors, colors, and stains—even from rich sauces and spices. After use, a quick rinse or dishwasher cycle restores the container’s crystal-clear finish, maintaining a fresh, hygienic storage solution free from lingering odors and ghost stains.
- One-Click Locking Clips: Featuring ergonomic stainless steel side clips, these 400 ml containers lock and unlock effortlessly with a single hand and click. The corrosion-resistant hinges provide a secure, spill-proof seal every time, making them perfect for busy kitchens, office meals, and outdoor picnics.

CARE
CARE
Before First Use
• Wash with mild detergent, rinse well, and dry thoroughly.
• If the lid sticks or the gasket pops out at first, that’s just the airtight seal settling—not a defect.
Cleaning
• Safe on the top rack of your dishwasher (delicate/low-heat cycle).
• For hand-washing, use non-abrasive soap and a soft cloth—no scouring pads.
• To clean under the gasket, gently pry it out with a blunt tool, rinse, air-dry completely, then snap it back in place. Always ensure both lid and gasket are fully dry before storing.
Cautions
• Never place glass directly on an open flame.
• Don’t microwave with lids locked—leave vents open.
• Avoid over-filling (keep below 70% full in the freezer to allow for expansion).
• Don’t stack non-nesting containers or slam them together.
• For oven-safe models, let chilled containers come to room temperature before heating."






Fully Airtight & Leak-Proof
Every Glasslock container features airtight clip-lock lids that create a rock-solid seal—no spills, no cross-contamination, and no wasted space in your fridge or bag. The tempered glass bodies resist staining and odors, so leftovers taste as fresh days later as the moment they were stored. Designed for demanding kitchens, Glasslock maintains its clarity and strength through countless low-heat, top-rack dishwasher cycles.

Handles extreme temperatures
Glasslock’s tempered glass design handles extreme temperatures—from freezer chill to microwave reheat—without cracking or warping. All models are oven-safe up to 120 °C, doubling as baking dishes and serving bowls for seamless prep-to-table transitions. The airtight lids lock in steam and heat for perfect reheating, preserving texture and flavor in casseroles, soups, and more.

Pure, Recyclable Materials
Glasslock containers are made from natural materials like silica, soda ash, and limestone, making them fully recyclable and gentle on the planet. Tempered for exceptional strength, each piece withstands impacts and thermal shocks far better than ordinary glass. The ultra-clear bodies and lids are 100% BPA-free and free of harmful additives, so your food stays pure and safe. With precision-engineered clip-lock lids and silicone gaskets, they lock in freshness, moisture, and aromas while preventing leaks—even when packed with soups or sauces.
