ComSaf Glass Overnight Oats Jars, 300 ml, Set of 4 with Colour-Coded Lids

The 300 ml glass jars make it easy to prepare individual breakfasts or snacks ahead of time, while four different lid colours help keep portions and ingredients easy to identify in the fridge. Each jar has 270 ml of usable capacity, making the set a practical fit for overnight oats, yoghurt, fruit or other smaller portions.

The glass bodies pair with pink, green, blue and grey BPA-free polypropylene lids. A food-grade silicone seal gives each jar a tight, leak-proof closure for cold storage and carrying to work or school.

What matters most

Four matching jars give you a simple way to prepare several portions at once, rather than relying on one larger container and dividing food each morning. The colour-coded lids make it easier to tell your portions apart at a glance, whether you are organising different breakfasts or setting aside fruit and snacks. The 300 ml capacity, with 270 ml usable, suits a single serving of oats, yoghurt, chia pudding, nuts or fruit.

The glass is also useful beyond breakfast: it does not absorb unwanted smells and can hold dry-store ingredients such as seeds, grains, dried fruit and spices. The jars are stackable to help organise storage, and the set includes six white labels measuring 5.5 × 3.5 cm for marking contents. Buyers highlight the portion-friendly size and use for oats, yoghurt and fruit snacks, feedback on durability is mixed, so handle the glass jars with care in everyday use.

Care & maintenance

Both the glass jars and plastic lids are dishwasher-safe, the recommended position for the lids is the top rack. The silicone-sealed jars are designed for cold storage and are not suitable for microwave use. For a straightforward routine, prepare and chill a portion in its jar, then wash it in the dishwasher after use. This makes the set handy for repeated breakfast preparation without relying on disposable pots.

Best use cases

Prepare overnight oats in the evening for a ready-to-eat breakfast the next day, or fill a jar with yoghurt and fruit for a snack at work or school. The tight seal supports taking cold portions on the move, while the distinct lid colours help separate ingredients or servings in a shared fridge. If your main priority is keeping several small portions organised, these jars offer a more clearly labelled approach than storing everything in one large tub. They also work for pantry organisation when you want small amounts of dry ingredients close to hand.

It brings portioning, fridge organisation and portable cold storage together in one practical format.
