New Guardian C4 Premium Manilla 130gsm Peel & Seal Gusset Envelope, Pack 10

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.

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

Tough envelopes and stick well

Ripped really easy, just trying to add some A4 documents, would not buy again!
