Bercoor 25 Pack 8.5x11in Corrugated Cardboard Sheets, 2mm for Mailing Craft

• Pack Size: 25 sheets of brown corrugated cardboard, each 8.5 x 11 in (A4 size, 21.6 x 27.9 cm) and 0.08 in (2 mm) thick; bulk pack for mailing, packing and classroom craft use
• Structure And Strength: Three-layer E-flute corrugated board with kraft liners; rated 10 lb breaking strength, keeps photos documents and flat mail items from bending inside poly envelopes
• How To Cut And Store: Score with a bone folder or utility knife for clean edges, cut on a mat to protect surfaces; store flat in a dry room to prevent warping, moisture is the main cause of curl
• For Shipping And Crafts: Slip into poly mailers as stiffeners for prints and certificates, use as backer board behind framed art, build dioramas and school displays, or paint as wedding backdrop panels
• Eco Note: Made from recyclable kraft paper, brown tone suits natural-themed projects; if edges feel rough from die-cutting, sand lightly with fine grit for a smooth finish
