New Guardian Envelopes Heavyweight Peel and Seal Gusset 25mm 130gsm Manilla C4 (Pack 100)

I have used this brand before and they are excellent quality and quite capacious. I send out good in these rather than the plastic mailers as they offer better protection and keep the items flat.

Bought these to send a bundle of legal documents.They are far too flimsy - tear very easily - ended up using parcel tape around all of the edges.Won't buy again!

Exactly what I needed for storing sheet music. Sturdy and gussetted.

Good envelopes at a reasonable price.

Very prompt delivery, faster than advertised. Envelopes are as expected, and the package came with a little free gift of a screen cloth. Nice touch!

Arrived in very good time, not as good a standard as I was expecting but do the job I need them to.

These are tough envelopes and stick really well. They have a lot of room (they were bigger than expected). Good value for money
