The Three Pillars of Profit Protection


Low Unit Cost

Buying in bulk from us means you aren’t paying retail markups. Lower your cost-per-sale and keep more of your hard-earned money.

No Surcharge Design

Our bags are specially chosen to fit Royal Mail and Evri size templates. Avoid the dreaded £1.50+ ‘oversized’ penalty fees.

Reduced Returns

Cheap, thin bags rip in transit, leading to damaged items and forced refunds. Our thick co-extruded polymer ensures your item arrives exactly as as it was posted.
