Osmer Data Envelope A5 Slide Zip Assorted - 20 Packs of 12

Osmer lists the DEA5 as 240 x 180mm.

Osmer assorts the zips in 4 colours per dozen: blue, green, red and yellow.

Osmer describes the DEA5 as a waterproof zipper bag. We have no test data beyond Osmer's description.

The listing is 20 packs of 12 envelopes, which is one Osmer inner. Osmer confirmed (supplier, Oct 2026): the unit is a pack of 12 and the inner is 20 packs. Osmer packs 20 packs to an inner and 80 packs to a carton.

Osmer's product page for the DEA5 does not name the material. No environmental or safety certification is listed on Osmer's product page for this code, so we do not claim one.
