Keep the exact12-bag record
The selected Waitrose record 824828-652972-652973 is Bacofoil All Purpose Zipper Bags Medium 12 s, observed at£3.35. It declares 12 bags, medium 3 L capacity and 24 by 27 cm dimensions. This is not the 15-bag small zipper selection, the SafeLoc double-seal range or a bulk carton containing many retail boxes.
Read declared size without a fill guarantee
The price arithmetic is about 27.916667 pence per bag. Declared 3 L is a capacity description, not a promise that any rigid 3 L object will pass through the opening or that every fill can be sealed without headspace. Dimensions are source declarations;no actual usable-opening or gusset measurement was made here.
Retain freezer and care scope
The selected source describes freezing and reuse, including dishwasher care below 70°C and an up-to-ten-use claim. That does not establish microwave, oven, boiling or hot-fill permission. We do not turn a washing-temperature limit into a food-heating approval, or treat the maximum reuse claim as a guarantee for every received bag. The current maker page explicitly excludes microwave,combination and conventional ovens for this ZIPPER format.
Do not import another format’s instructions
Before repeating an order, keep medium, 12-count and the exact product record together. Check current received warnings and the maker’s current version if the pack differs. Marketing leak and tear-resistance statements remain attributed source claims;this site has not performed a seal, transport, liquid or food-storage experiment.
A purchase case to keep explicit
A buyer needing medium bags should keep 12-count and the maker’s 27 cm width/24 cm height orientation in the note. The retailer’s 24 by 27 cm order is the same pair of lengths, not a new measured opening. Neither source proves a particular rigid object will pass through the zip.
