Frequently Asked Questions
Can I really get mailers under $1 per unit?
Yes — many of these items hit sub-$1 per unit when bought in bulk bundles (25+ boxes or multi-roll tape packs). Prices fluctuate, so check current per-unit pricing and factor in storage and turnover before buying large quantities.
Are single-wall boxes strong enough for e-commerce?
Single-wall C-flute boxes are suitable for many lightweight to medium-weight items and offer excellent value. For very heavy, dense, or fragile goods, add internal cushioning or upgrade to double-wall for extra protection.
Should I use bubble bags or boxes for small fragile items?
Use bubble bags for small, compact fragile items where size and weight savings matter. For multiple items, oddly shaped pieces, or goods that need stamping or branding, a box with internal cushioning is usually safer and presents better to customers.
