This article covers Bilious (ビリアス) カスタムカスタマイズUSB Cフラッシュドライブ 50パック 32GB.

Overview

The Bilious Custom USB C Flash Drive 50-Pack is a bulk USB memory solution designed for businesses and organizations that need large quantities of branded storage. Available in 32GB, 64GB, 128GB, and 256GB capacities, it features a USB 3.0 interface with a 2-in-1 dual connector design that includes both USB-C and USB-A. The metal housing with a 360-degree rotating cap-less design adds durability and a premium feel, while water resistance provides extra protection. What sets this product apart is its customizability — you can have your logo or pattern printed on the drives, making it ideal for corporate giveaways, event handouts, or educational distribution. With claimed write speeds of 80-100 MB/s, it handles everyday file transfers with ease. The 50-pack format keeps per-unit costs low, making it a cost-effective choice for bulk orders.

Connectivity & Compatibility

The drive uses USB 3.0 (USB 3.2 Gen 1) and is backward compatible with USB 2.0 ports. Its dual USB-C and USB-A connectors mean it works with modern laptops, tablets, and smartphones that have USB-C ports, as well as older desktops and devices with standard USB-A ports. No driver installation is required — it is plug-and-play on Windows, macOS, Linux, and Chrome OS. Water and dust resistance add to its versatility, making it suitable for outdoor events, field work, or any environment where exposure to the elements is a concern. The rotating metal cap protects the connectors when not in use and eliminates the risk of losing a separate cap.

Best Use Cases

Corporate marketing and promotional teams: Ideal for distributing branded USB drives at trade shows, conferences, or as client gifts. The 50-pack allows you to order in bulk at a reasonable per-unit cost. However, custom printing requires a separate ordering process, so plan ahead for lead times. Educational institutions and event organizers: Perfect for handing out course materials, event schedules, or promotional content to students or attendees. The dual USB-C/USB-A compatibility ensures it works with a wide range of devices. Not suitable for individuals who only need one or two drives. * Non-profit organizations and community groups: Useful for distributing information kits or fundraising materials at community events. The water-resistant design adds durability for outdoor use. Consider whether 50 units is the right quantity for your event size before ordering.

Things to Consider

This product is sold exclusively as a 50-pack, so it is not suitable for individuals who need just one or two drives. If you only need a small quantity, look for single-pack USB drives instead. Custom printing requires a separate order process, and you should verify minimum order quantities and delivery timelines with the seller. While the drive is rated for USB 3.0 (USB 3.2 Gen 1), real-world transfer speeds may be lower than the claimed 80-100 MB/s, especially with smaller files or older hardware. For users who frequently transfer large files, a faster USB 3.2 Gen 2 or USB4 drive would be a better choice. The water resistance is splash-proof level, not full submersion. The metal body is sturdy but does not guarantee protection against drops or impacts. Handle with care to avoid damage to the internal components.
