The Slice Mini Box Cutter is a compact, go-anywhere box opener designed for everyday packages at home, work, or on the move. It uses a 100% zirconium oxide ceramic blade with Slice’s proprietary finger-friendly edge to help reduce accidental nicks while still slicing through tape and packaging cleanly.

Beyond boxes, it’s handy for opening common household packaging like food wrappers, plastic containers, and clamshell packaging. The manual retract design keeps the tool simple and pocket-friendly, and the lightweight handle is reinforced for durability. A built-in magnet lets you park it on a fridge or other magnetic surface so it’s easy to find when a delivery arrives.

Unlike metal blades, this ceramic blade won’t rust and is designed to last up to 11x longer than metal package openers—making it a practical, low-fuss choice for frequent unboxing.
