Box Buddy Universal Clip-On Card Box Dividers

Organize your card boxes without sacrificing valuable storage space. Box Buddy dividers clip directly onto the side wall or divider wall of compatible cardboard card boxes, giving you a simple way to separate cards by set, sport, team, player, rarity, collection, inventory category, and more.

Box Buddy is available in two clip sizes to accommodate different cardboard box constructions. Both versions feature the same redesigned low-profile shape and work with compatible vertical and horizontal card storage boxes.

Works with Vertical and Horizontal Boxes

The redesigned low-profile Box Buddy works with compatible cardboard card boxes whether your cards are stored vertically or horizontally. There is no need to purchase a different divider based on box orientation.

Simply choose the correct clip size for the thickness of your box wall, attach the Box Buddy, and reposition it whenever you need to reorganize your collection.

Unlike traditional full-size dividers, Box Buddy does not require you to force a large divider between tightly packed cards. The clip-on design keeps the divider above the cards while helping preserve valuable storage space inside the box.

Choose Your Box Wall Type

Standard / Single-Wall
Best for traditional cardboard card storage boxes with thinner single-layer walls. This is the original Box Buddy clip size.

Thick / Double-Wall (BCW Multi-Row)
Designed with a wider clip opening for thicker cardboard walls and reinforced dividers, including the divider walls used in many BCW multi-row card storage boxes.

Both versions work with compatible vertical and horizontal boxes. The only difference is the width of the clip opening.
