Questions about this item

Does the 28 lb paper weight and center seam hold up in a Neopost inserter running all day without jamming?

Yes, the 28 lb sulphite stock with center seam is designed for continuous Neopost machine insertion and resists tearing during high-volume runs.

Do I need a specific Neopost inserter model or any other equipment to use these envelopes?

They require a Neopost-compatible inserter that accepts 9.5 x 12.5 inch open-end catalog envelopes with a remoistening seal; no other equipment is needed.

Will the 9.5 x 12.5 inch size and remoistening seal work with older catalog envelopes I already have in stock?

The dimensions match standard catalog envelope sizing, so they stack and feed alongside existing 9.5 x 12.5 inch stock; the remoistening seal functions the same way.
