It sounds like you’re describing a Black Waterproof Fly Box from Angling Designs Inc. that comes pre-loaded with 22 flies. Here’s a breakdown of what this might include and considerations for potential buyers:

Key Features:
1. Waterproof Design – Likely made from durable, sealed materials (e.g., ABS plastic or silicone gaskets) to protect flies from moisture, rust, and damage.
2. Compact & Portable – Designed for anglers to carry in a vest, pack, or pocket while fishing.
3. Pre-Loaded Flies – Includes 22 flies, possibly a mix of popular patterns (e.g., dry flies, nymphs, streamers) for versatility.
4. Secure Storage – May feature foam inserts, magnetic panels, or slotted compartments to keep flies organized.

Potential Use Cases:
– Travel-Friendly: Great for backpacking or wading where space is limited.
– Beginner-Friendly: Pre-loaded flies save time for those new to fly selection.
