This article covers EASTBULL 16GB FAT32 USB2.0 & Type-Cフラッシュドライブ 20パック 2イン1デュアルフラッシュドライブ 16GB バルク USB-A + USB-C サムドライブパック スマートフォン コンピューター タブレット Mac対応 (ブルー).

Overview

The EASTBULL 16GB FAT32 USB2.0 & Type-C Flash Drive 20-Pack is a bulk bundle of twenty dual-connector USB drives. Each drive integrates both a USB-A and a USB-C plug, making it compatible with older computers as well as modern laptops, tablets, and smartphones that rely solely on USB-C. The pack comes in blue with a simple, business-like design. Sequential read speeds reach 15–25 MB/s and write speeds 10–15 MB/s, which is typical for USB 2.0 thumb drives. This product is clearly aimed at organizations that need a large quantity of affordable, reliable flash drives for distribution. With a per-unit cost of roughly ¥724 (≈US$5), it offers a very low barrier for schools, offices, or event planners. The drives ship preformatted as FAT32, so they work immediately on Windows, macOS, and Android without additional software.

Connectivity & Compatibility

The flash drives use the USB 2.0 interface and feature a 2-in-1 connector design: one end is a standard USB-A plug, the other is a USB-C plug. This allows direct connection to virtually any device with a USB port — from legacy desktop PCs to the latest USB-C-only MacBooks and Android tablets. Important limitations: the drives do not work with Apple Lightning ports, and Android devices may require enabling USB OTG (On-The-Go) in the system settings. All major operating systems that support USB mass storage will recognize these drives, including Windows, macOS, Linux, Android, and Chrome OS. Because they are formatted as FAT32, individual files larger than 4 GB cannot be stored, but this is not an issue for typical document, photo, or presentation workflows.

Product Info

The EASTBULL 20-pack is currently available on Japan at ¥14,476 (tax included). The exact release date is not publicly disclosed, but the product appeared on the market around 2025. Warranty terms are not explicitly stated; buyers should rely on ’s standard return policy for defect coverage. This is an entry-level product. It is not designed for high-speed transfers or heavy workloads. The internal memory uses TLC NAND flash, rated for approximately 3,000–5,000 program/erase cycles. The casing is made of ABS plastic with an aluminum alloy swivel clip that protects the connectors and adds impact resistance. Each drive is lightweight and includes a keychain loop.

Best Use Cases

Educational Institutions: Perfect for handing out course materials, textbooks, or software installers to students in bulk. The 16 GB capacity is ample for documents, and the dual-connector ensures compatibility with both school-issued laptops (USB-A) and student-owned tablets (USB-C). Corporate Document Distribution: In offices where internal file-sharing systems are restricted or slow, these drives offer a quick physical alternative for meeting handouts or confidential data transfers. However, they should not be used for backup or large video files due to the USB 2.0 speed bottleneck. Event Giveaways & Promotional Merchandise: A cost-effective, branded giveaway for conferences, trade shows, or product launches. The blue shell can be customized with stickers or a laser-etched logo to reinforce brand recall. Emergency Boot Drives for IT Staff: IT technicians can preload each drive with a lightweight Linux ISO or system recovery tool and keep a pack ready for rapid troubleshooting across multiple machines. USB 2.0 is perfectly adequate for booting and running diagnostic utilities.
