Frequently Asked Questions

Are the Black+Blum Glass Food Containers leakproof?
Yes. Each container uses a vacuum-sealed lid lock that is designed to be 100% leakproof and airtight, helping prevent spills while keeping food fresher for longer.

Can the glass containers go in the oven?
Yes. The borosilicate glass bases are oven-safe up to a maximum temperature of 250°C. The lids must not be placed in the oven.

Can I use the containers in an air fryer?
Yes. The glass bases can be used in an air fryer, but the lids must be removed before cooking.

Are the containers microwave-safe?
Yes. The glass containers are microwave-safe. The lid has also been designed for microwave use to help reduce splatter, but the lid lock must remain open to prevent pressure build-up and allow steam to escape.

Can the containers be stored in the freezer?
Yes. The borosilicate glass is suitable for freezer storage down to -20°C. Avoid overfilling the containers when freezing food.

Can I move a container directly from the freezer to a hot oven?
No. Frozen glass should be allowed to defrost before being placed into a preheated oven. Sudden temperature changes should be avoided to reduce the risk of thermal shock.

How much thermal shock can the glass withstand?
The glass is resistant to thermal shock up to 200°C. Avoid placing hot glass onto cold or wet surfaces, putting hot glass under running water or exposing it to sudden severe temperature changes.

Are the lids dishwasher-safe?
Yes. The lids can be cleaned in the dishwasher and should be placed on the top rack. The seals are also removable for more thorough cleaning.

How do I open the vacuum-sealed lid?
Press the button on the lid to release the locking mechanism and break the vacuum seal, then slowly lift the lid upwards.

Are these containers compatible with Black+Blum stainless steel meal prep boxes?
Yes. The containers and lids are compatible with Black+Blum Stainless Steel Meal Prep Boxes, excluding the Square and Bowl-shaped ranges.

Can the glass containers be used on a hob or grill?
No. The containers should not be used over a direct flame, on a hob, under a grill, in a toaster oven or beneath a browning element.

Returns — Consumer Customers

This section applies to purchases made by individuals acting as consumers, not in the course of a business.

Right to Cancel

Under the Consumer Contracts Regulations 2013, you have the right to cancel your order within 14 days of receiving your goods. You will be responsible for the return shipping costs.

To be eligible for a refund, items must be returned unused, in perfect condition, and in their original, unopened packaging. Delivery charges are non-refundable. Please allow up to 14 working days for the return and refund process.

To initiate a return, please contact us at contact@redber.co.uk or call 01483 80 85 80, quoting your order number (found in your order confirmation email and packing slip).

Exemptions from the Right to Cancel

The right to cancel does not apply to:

• Goods that are perishable or have a short shelf life
• Customised or personalised items
• Items sealed for hygiene reasons that have been unsealed after delivery
• Services that have already been completed

As all our coffee is roasted to order and customised for your chosen brew method, some products may not be eligible for cancellation. This does not affect your statutory rights if a product is faulty or not as described.

Returns — Business Customers

This section applies to all purchases made by businesses, sole traders, partnerships, limited companies, or any buyer purchasing in the course of a trade or business.

No Statutory Right to Cancel

The Consumer Contracts Regulations 2013 and the Consumer Rights Act 2015 do not apply to business-to-business (B2B) transactions. Business customers do not benefit from a statutory 14-day cooling-off period or any equivalent right to cancel simply because they have changed their mind.

Our B2B Returns Policy

Redber does not accept returns from business customers unless a return has been expressly agreed in writing by Redber prior to the goods being returned.

In addition to the above, we will not accept any return where:

• The packaging has been opened, broken, or tampered with in any way
• The goods have been used, prepared, brewed, or consumed to any extent
• The goods are perishable or have a short shelf life (which applies to all roasted coffee)
• The goods were roasted, blended, or ground to a custom specification for that order

These conditions apply regardless of the reason for the return request, except where the goods are confirmed to be faulty or not as described (see below).

Faulty or Misdescribed Goods

Nothing in this policy limits or excludes Redber's obligations under the Sale of Goods Act 1979. If goods supplied to a business customer are of unsatisfactory quality, not fit for purpose, or materially not as described, the business customer retains the right to:

• Reject the goods and obtain a refund, or
• Request a repair or replacement

Any such claim must be notified to us in writing within a reasonable time of delivery, and we reserve the right to inspect the goods before agreeing a remedy. Photographs of any defect should be provided at the point of notification.

How to Request a Return

If you believe your order qualifies for a return under the limited circumstances set out above, please contact us in writing at contact@redber.co.uk before returning any goods, quoting your order number. Goods returned without prior written authorisation will not be accepted and may be returned to sender at the business customer's expense.
