Category: Storage Boxes & Travel Cases

We manufacture a custom multi-functional EVA hard case designed for trading card and game card protection during travel and outdoor use. The EVA construction forms a rigid, waterproof shell that shields card collections from impact and moisture, while the large-capacity interior accommodates organized storage of game cards. Black is the standard color, and dimensions are built to order so the case fits specific deck sizes or retail assortments. This product targets distributors, game retailers, and promotional buyers who need a durable carrying solution rather than a soft pouch.


EVA is a closed-cell foam that does not absorb water, so the case keeps cards dry in rain or damp camping conditions while cushioning drops.
The waterproof attribute is confirmed in the product data, making the case suitable for outdoor travel and camping where soft fabric bags fail.
Size is listed as custom, allowing the interior cavity and exterior dimensions to be built around specific card counts or game formats.
The multi-functional large-capacity design stores full collections in one rigid case instead of multiple small boxes.
Logo and color customization are offered for buyers who need retail-ready branded cases rather than generic storage.

Black is the standard color; Pantone color matching is offered for buyers who need cases to match brand or product line colors.
Because size is listed as custom, interior cavity dimensions and compartment layout can be adjusted to specific card formats or counts.
EVA thickness and shell construction can be discussed with our factory to balance weight, rigidity, and protection for the intended use.

Cases are packed for export from Guangdong, China, with packaging options that can include standard export cartons, retail-ready boxes, or display packaging depending on the buyer’s channel. Because the product is custom-sized, packaging dimensions are aligned to the finished case size to reduce void space and shipping volume. Our factory coordinates packaging format with the order specification so cases arrive ready for retail or distribution without repacking.

Our factory works with EVA as a primary material, so shell thickness, rigidity, and waterproof construction are controlled at the molding stage rather than assembled from generic components.
Size is a build-to-order parameter, meaning our production line is set up to tool and mold cases around each buyer’s card format rather than forcing a stock size.
Logo and color customization are handled in-house, keeping branding consistent with the case construction.
The waterproof feature is verified in the product data, and the case is specified for travel and camping, so our factory builds to outdoor durability requirements.
