12x12 Inch Corrugated Cardboard Sheets, 55 Pack, Made in USA, 100% Recycled Brown Squares for Crafts and Shipping

These are true 12 by 12 inch brown corrugated sheets, made in the USA from 100% recycled board by a packaging company that's been at it since 1978. A flat, stiff backing cut to the exact size on the label, that you trim down for whatever you're shipping or making. In a category where half the returns come down to sheets arriving the wrong size or thinner than the photo, these are exactly what's shown - a real 12 x 12, single-wall and light enough not to pad your shipping weight, stiff enough to keep prints, photos, and documents from bending. Cut one to a mailer or divider, or stack two for cushion. Scrapbookers, teachers, and party planners use them as a rigid 12x12 base that matches the standard page and takes paint, marker, and glue without warping. Around the house they work as drawer dividers, shelf liners, and write-on backing, and lie flat in storage instead of curling like poster board. Chase Partitions makes these on the same American line it's run for over forty years - so the size, weight, and board are what you see here. Common questions: Q: Are these made in the USA and recycled? A: Yes - true-to-size corrugated sheets made in the USA from 100% recycled board by Chase Partitions, a St. Louis manufacturer since 1978. Most multipacks in this category are imports. Q: How thick are they - are they heavy-duty? A: Single-wall corrugated, about 1/16 inch - stiff and flat, made to back and protect flat items and cut easily for crafts and mailers. Not a heavy double-wall shipping board; stack two or three for more rigidity. Q: Are they true to size? A: Yes - cut to the size on the label: a true 8 x 10 or a true 12 x 12, not rounded or undersized. Q: Can these be cut down? A: Yes - score and snap, or run a box cutter once, to a mailer, backing board, divider, or craft shape. Offcuts work as small pads. Q: Will a 12x12 work for vinyl records? A: The 12x12 is a true 12 by 12 inches. LPs run about 12.4 inches, so a record sits slightly proud - good as a stiffener inside a mailer, but size up for full coverage. Q: How are these different from poster board or chipboard? A: Corrugated has a fluted inner layer, so it's stiffer than flat poster board and lies flatter; lighter and easier to cut than heavy chipboard. Q: What can I use these for at home or the office? A: Drawer dividers, shelf liners, layer pads, backing for frames and certificates, and a base for kids' projects. The matte face takes pen and stamp. Q: Which pack should I buy? A: 55 suits occasional use or one project; 105 and 210 lower the per-sheet cost for regular shippers, classrooms, and shops. Two sizes, three counts each.

• TRUE 12X12, MADE IN THE USA: These are true 12 x 12 inch corrugated sheets - cut to the size on the label, made in the USA from 100% recycled board. If you've had cardboard squares arrive a half-inch short or flimsier than the photo, that's the gap Chase Partitions closes. Each trims to a mailer, divider, or album page with scissors. Stiff but light single-wall. Exactly what's shown.
• STIFF ENOUGH, LIGHT ENOUGH: Slide one behind a print or photo and the corners stop bending, without the postage weight of a heavy double-wall board. A single-wall sheet built to keep flat things flat and stay easy to cut - stack two or three for more cushion.
• THE 12X12 CRAFTERS REACH FOR: If you scrapbook or run camp and classroom crafts, a true 12x12 board that matches your page beats cutting up old boxes by hand. Takes paint, marker, and glue without warping, lies flat instead of curling, cuts clean for banners and decor.
• PACKED FOR THE NEXT MOVE: Mid-move, these line boxes, wrap furniture corners, and cushion fragile pieces without adding much weight. Day to day they're drawer dividers, shelf liners, and write-on backing - and unlike poster board, they lie flat in storage.
• FROM A 1978 USA PACKAGING MAKER: Chase Partitions has cut corrugated and chipboard packaging in St. Louis since 1978, family-run in its second generation. Every sheet comes off that American line, 100% recycled - what arrives matches what's pictured, not an anonymous import.
