## Products

- [Guitar Box, 20" x 8" x 50" Side Loading](https://boxesfast.org/) — ASIN B077BXWCZS. Slide a framed mirror or a guitar in a soft case end-first through the open end of this 50-inch carton and it lands flat instead of dropping past the flaps.
- [Shipping Box, 12" x 12" x 2" Double Wall](https://boxesfast.org/) — ASIN B07864XX9G. Fold this flat white mailer shut with your hands in a few seconds: no tape, no glue, no staples, which is why estate-plan binders and laser-engraved goods leave small offices in it.
- [Tall Box, 16" x 16" x 30"](https://boxesfast.org/) — ASIN B077BWS2MF. Stand a floor lamp, a set of congas, or a season of bedding upright in this tall carton and the 30-inch height does work a cube cannot.
- [Double Wall Cube, 16" x 16" x 16"](https://boxesfast.org/) — ASIN B077BXWR9K. Drop 40 lbs of hardcover books into this double-wall cube and the bottom seam holds, because two fluted layers sit under the load instead of one.
- [Tall Narrow Box, 4" x 4" x 28"](https://boxesfast.org/) — ASIN B077BX23PX. Feed golf clubs, fishing rods, or a length of shelving into a square opening that runs 28 inches deep and skip the mailing tube entirely.
- [Double Wall Box, 24" x 16" x 16"](https://boxesfast.org/) — ASIN B077BXWR9L. Ship a 45-lb label printer or a crate of vinyl records in this long double-wall carton and the 275#/ECT-48 board carries 100 lbs of breaking strength under the load.
- [Flat Box, 22" x 22" x 6"](https://boxesfast.org/) — ASIN B077BVTF2J. Lay an 18-inch wreath into this shallow carton with room above the bows and nothing arrives flattened, which is why wreath sellers reorder the same size every autumn.
- [White Tuck-Top Mailer, 8" x 3" x 2"](https://boxesfast.org/) — ASIN B07822STMH. Fold a mailer shut in a few seconds with no tape, no glue, and no staples, then reach for the next: high-volume sellers run about 100 of these a week off a single table.
- [Flat Box, 14" x 8" x 4"](https://boxesfast.org/) — ASIN B077BW3SHH. Pack a pair of sneakers, a stack of paperbacks, or a folded garment into this shallow depth and skip the void fill a deep carton demands.
