New Challenge "Danbo-ru Plus" to Solve Logistics Issues for E-commerce Businesses

Adopts high-quality materials designed for courier transport. High-strength design resistant to stacking and pressure.

Changing the "invisible losses" of e-commerce logistics, starting with cardboard boxes.

On July 1, 2026, Plus One (brand name: Danbo-ru Plus) will launch a crowdfunding campaign for "Danbo-ru Plus," a high-strength cardboard case, to solve logistics challenges faced by e-commerce businesses and handmade artists, such as "product damage during shipping," "return and reshipment costs," and "excessive packaging."

With the recent expansion of the e-commerce market, the number of parcels handled by courier services is increasing. However, due to driver shortages and the need for delivery efficiency in logistics operations, the packing density of parcels is increasing, leading to frequent instances of crushed boxes and damaged products during transport. As a result, many small businesses are forced to bear the costs of returns and reshipments, facing a situation where they lose potential profits. We view this problem not merely as an issue of cardboard quality, but as a societal challenge.

The first thing a customer sees is not the product, but the "box."

A "crushed box" not only damages the product but also the business's credibility. In e-commerce, the first thing a customer sees is not the product but "the box that arrived." Even if the product is intact, a damaged box can cause anxiety for the customer. Especially for sole proprietors and handmade artists, a single negative review can have a serious impact on sales.

We recognize that "the quality of the box is part of the brand value,"

and we are concerned about the following losses caused by product damage:

- Returns processing

- Reshipment processing

- Inquiry handling

- Lowered review ratings

- Reduced repeat purchase rates

The negative cost chain created by insufficient strength

Many low-priced cardboard boxes currently in circulation are of insufficient strength, forcing shippers to use excessive cushioning materials, which leads to the following problems:

- Increased packing time

- Increased packing costs

- Increased waste

In other words, the lack of strength in cardboard boxes is one of the causes of "excessive packaging."

Crushed boxes, damaged products, negative reviews, reshipments—an invisible chain of costs caused by weak cardboard boxes.

"Strong boxes" eliminate waste in logistics.

Danbo-ru Plus was developed with the aim of "reducing waste in the entire logistics process by providing strong boxes at a fair price." By using high-quality materials designed for courier transport and incorporating reinforcing materials in the core, we have achieved higher compressive strength compared to general commercially available cardboard boxes.

Our goals are the following four points:

- Reduced risk of damage during transport

- Reduced use of cushioning materials

- Reduced costs for returns and reshipments

- Enhanced brand value

We aim to create cardboard boxes that are chosen for their quality, not for price competition. We will create "strong boxes" that benefit sellers, buyers, and shipping companies alike.

Logistics quality is an investment, not a cost.

This crowdfunding campaign is not just about selling a product; it's about spreading the idea that "logistics quality is an investment, not a cost." The funds raised will be used to secure the initial manufacturing lot, establish an Amazon sales system, expand the product lineup, and conduct awareness activities for logistics improvement.

We will provide an "environment where shipping can be done with peace of mind" and protect the trust of e-commerce businesses and everyone who handles products. After the crowdfunding campaign ends, we plan to start selling on Amazon and develop a wide range of sizes. We will spread the new common sense that "strength equals Danbo-ru Plus" and contribute to improving logistics quality in Japan.
