Size guide – which parcel bag do I need?

Why sellers choose iSOUL blue parcel bags

• Permanent self-seal strip: peel and press – no tape needed. Once sealed the parcel bag can't be opened without tearing, so parcels are tamper-evident.
• Fully opaque: blue outside, black inner lining, so nobody can see what's inside.
• Water and dirt resistant: protects items from rain and grime during delivery.
• Perfect parcel bags for clothes: ideal for posting clothing, accessories and other soft goods that don't need a box.
• Professional look: a clean, neutral blue that suits menswear, kidswear, tech accessories and business orders, and stands out more than plain grey.
• Works with all couriers: Royal Mail, Evri, DPD, Yodel, InPost and Vinted drop-off points.
