Sleeve Boxes, also known as slipcases or drawer boxes, consist of two main parts: an outer sleeve and an inner tray that slides in and out like a drawer. This design enhances the unboxing experience while maintaining structural integrity and a sleek appearance. Sleeve boxes are widely used in luxury product packaging, including tech accessories, skincare items, confections, and promotional gifts. Their compact, modern form makes them perfect for retail displays and brand storytelling.
