Most Vinted sellers use 10×14" for dresses and jeans, 9×12" for T-shirts and tops, and 12×16" or larger for jumpers and coats. Which pack size should I buy? The 25 and 50 packs suit occasional sellers. Regular sellers usually choose 100, and the 500 or 1000 pack gives the lowest price per bag for high-volume businesses. What's the difference between mailing bags, postage bags and parcel bags? Nothing – mailing bags, postage bags, postal bags, parcel bags and poly mailers are all names for the same self-seal plastic bags used to post items. Can I send these as a Royal Mail Large Letter? The 6×9" and 9×12" bags can qualify, as long as the packed parcel stays within Royal Mail's Large Letter limits (353 × 250 × 25 mm, up to 750 g). Please check Royal Mail's current rules before posting. Is delivery free? Yes – UK delivery is free on every order, with no minimum spend. Need a bigger quantity?
