## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for sending books by post
*by L***Y on 3 May 2025*

Exactly what I needed to send parcels of books by post. Sturdy, shape into a good box and will take several books of different sizes. Worked very well for sending signed books to fans. I've ordered another set.

### ⭐⭐⭐⭐⭐ Versatile
*by T***. on 26 December 2024*

Brilliant quality, versatile envelopes. Really good for a variety of different stuff. The glue to seal it is very string and there's no risk of it opening mid-post, no additional tape required. They're quite light and do the job well.

### ⭐⭐⭐⭐ Good quality
*by S***H on 21 December 2024*

Good quality easy to use, but very overpriced hence the 4 stars review
