## Customer Reviews

### ⭐⭐⭐⭐⭐ Great
*by  on Reviewed in the United Kingdom 29 May 2022*

Great value, does the job!

### ⭐⭐⭐ Good, but NOT suitable for 'up to A3' as listed
*by  on Reviewed in the United Kingdom 11 January 2021*

The quality is good, but as the length itself is 30cm, and A3 paper is 30cm wide, these tubes are not suitable for A3, as the end caps protrude inside the tube - and I bought them in a hurry for A3, needing them urgently. Annoying. Ideal for A4, but no bigger.

### ⭐⭐⭐⭐⭐ Poster
*by  on Reviewed in the United Kingdom 25 June 2020*

Fabulous tubes for mini posters
