Business Source #97 Clasp Envelopes

These heavy-duty clasp envelopes measure 10 by 13 inches and come in a 100-count box. The 28 lb Kraft stock provides durable protection for documents during transit or storage. They suit offices, schools and home users who need reliable large-format mailing supplies. The open-end design allows quick insertion of bulky files or catalogues.

Reinforced rust-resistant metal clasp

A reinforced metal clasp with rounded edges is plated for rust resistance to withstand repeated opening and closing. Deep gumming on the large flap creates a secure seal that resists splitting in normal handling. The sturdy 28 lb construction resists tearing when stuffed with heavy paperwork. No power, cooling or noise considerations apply to this passive paper product.

100-count box of 28 lb Kraft envelopes

Each box contains exactly 100 envelopes sized to the #97 standard at 10 x 13 inches. Buyers who need smaller quantities, different closure types or lighter paper weights should look elsewhere. The clasp closure is not suited for automated mailing equipment that requires peel-and-seal or moistenable glue flaps.

Questions about this item

How do I seal the 10 x 13 clasp envelope so documents stay secure?

Moisten the deep gumming on the large flap, press firmly to seal, then bend the reinforced metal clasp prongs flat against the back for a double closure.

Will the clasp on these #97 envelopes rust if stored in a humid office?

The metal clasp is plated for rust resistance, so normal indoor humidity will not cause corrosion; replace only if the plating is scratched or the prongs bend.

At what point does the 28 lb Kraft paper show wear when the same envelope is reused daily?

Repeated folding at the flap crease and clasp-hole stress will cause fibre fatigue first; expect the paper to tear or the clasp to pull through after several heavy reuses.
