How to use

Place the item flat inside the envelope, ensuring edges and corners are protected from sharp contact.

Usage recommendations

Use these mailing bags for lightweight, non-fragile items and documents where cost-effective, moisture-resistant packaging is sufficient. Do not rely on these envelopes for sharp-edged or heavy products without additional protection; choose reinforced packaging for fragile or high-value items. Store unopened packs in a cool, dry place away from direct sunlight to preserve adhesive performance.
