### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality! 5 stars
  

*by D***A on Reviewed in the United Kingdom on 13 January 2018*

These postal mailing bags are very good quality - nice thick polythene that doesn't tear easily. These bags measure 40.6cm x 30.5cm and are great for sending Royal Mail small parcels (45cm x 35cm) . I have also used these as a large letter for posting flat items, but had to tape up the sides slightly to make them smaller than 35cm x 25cm, which is Royal Mail large letter size.Peel and Seal self-adhesive strip makes them very quick and easy to use.These bags are extremely handy and I always have a stock of them at the house in case I need to post something.
