This is the most common corrugated box style, with all flaps being the same length from the score to the edge. The outer flaps on the top and bottom of the box meet in the centre and can be closed with tape, glue, or staples. Excellent for packaging a wide range of products, from FMCG to horticultural to industrial. Ideal for shipping small individual items like cups and mugs, as well as books. It is also the least expensive to produce.
