### ⭐⭐⭐⭐⭐ good value

### ⭐⭐⭐⭐⭐ Great value, no complaints.
*by S***N on 27 January 2026*

Great value, no complaints.

### ⭐⭐⭐⭐ Be careful of adhesive
*by N***E on 30 December 2023*

These are cheap envelopes with a self seal on them. I have bought many in the past but lately my last 4 boxes had issues. First of all nearly all of the envelops were stuck together making it difficult to separate without damaging others. Secondly the adhesive, we found that after a day or two the adhesive would come unstuck so had to tape them down. Hopefully this was maybe a bad batch, or they were left in damp conditions prior to delivery?
