## Customer Reviews

### ⭐⭐⭐⭐⭐ As described
*by B***W on 15 January 2025*

The bags arrived by post and we're well packaged. The bags are true to size and surprisingly strong for the thickness of the material. I have only used them for putting my bread rolls in to prove. I find I can reuse them which is an added bonus.

### ⭐⭐⭐⭐⭐ Good quality
*by J***G on 11 February 2025*

Good quality bags.

### ⭐⭐⭐⭐ OK
*by G***B on 5 October 2024*

OK for what I wanted, but I expected a thicker grade of plastic to store bread. A bit thin to be reusable.
