I have been trading for the past 15+ years specialising in selling glassine envelopes (made by Lindner in Germany)
I am now building up a large stock of glassine Envelopes manufactured exclusively in the UK.
They are superb quality and look good as well!
I now also have Peel and Seal glassines in 3 sizes-also made in the UK by the same manufacturer.
Bespoke sizes can be made up to a maximum of 127 x 225 and subject to a minimum order of 10000
