Plano 3640 Waterproof Stowaway - Clear Waterproof Compartment Box

Our review of the Plano 3640 Waterproof Stowaway finds it best suited for anglers, hobbyists, and anyone who needs organized, protected small-part storage on the go; the single biggest reason to buy is its reliable seal combined with adaptable compartments that keep tackle and small items dry and organized. The compact footprint slips into most tackle bags and packs, and the clear polypropylene lets users identify contents at a glance while the Dri-Loc O-ring and tight cam latches deliver a waterproof closure you can trust in wet conditions.

Key Features

• Dri-Loc O-ring seal: Provides a continuous waterproof barrier so contents stay dry even in damp environments.
• Three cam-action latches: Tight-closing latches ensure the lid compresses the seal for dependable protection during transport.
• Adjustable compartments: Five to twenty configurable compartments let users customize internal space for small tackle, markers, or magnets.
• Clear polypropylene body: Durable, rigid material and transparent construction make it easy to see contents without opening the box.
• Low-profile size: At roughly 10-3/4 in by 7-1/4 in and 1-3/4 in high, it fits well in most tackle bags and storage areas.

Who It's For

This box is ideal for freshwater and saltwater anglers who need a slim, waterproof organizer for terminal tackle such as swivels, weights, and small lures. It also serves craft hobbyists and technicians who want a compact parts case that resists moisture and keeps items visible during fieldwork.

Those who require larger storage for bulky lures, long tools, or dozens of large components should look for a deeper or larger box; likewise, if absolute crush resistance under heavy loads is a priority, a heavy-duty molded case would be more suitable than this low-profile stowaway.

Pros & Cons

Pros

• Waterproof Dri-Loc O-ring and three cam latches deliver dependable moisture protection as customers report.
• Adjustable 5-20 compartments with 15 removable dividers offer flexible organization for a variety of small items.
• Clear, sturdy polypropylene and compact dimensions make it a good fit in most tackle bags and easy to inspect at a glance.
• Good value for the combination of seal, build quality, and storage capacity customers mention.

Cons

• Shallow overall height (1-3/4 in) limits storage to small items and may not fit taller components.
• Clear plastic shows scratches and scuffs over time, so it won't remain cosmetically pristine with heavy use.
