Mailing bags, padded envelopes and card mailers ranked for the small items most UK home sellers post, with the reason for each pick.
Most small parcels from a home seller go out in one of four mailers: a grey plastic bag for clothes, a padded envelope for small hard items, a rigid board-backed mailer for cards and prints, or a paper bag for buyers who want less plastic.
All four are cheap. Packs run from about £8 to £13 for grey bags up to £18 to £28 for paper ones. The right one keeps the item safe and the parcel in the cheapest postage size.

Each step in the order you'll need it.
Folded clothing goes in a grey bag. A phone case, a ring box or a small figure goes in a padded envelope. Cards, photos and prints go in a rigid mailer so they cannot bend.
If an item could break, post it in a box. Mailers protect from scuffs and bends, and give way when crushed.
Royal Mail’s Large Letter size allows up to 353 × 250 × 25 mm and 750 g. A sleeved, top-loaded card in a C6 board-backed mailer usually fits well inside that.
Padded envelopes can push past 25 mm thick once filled. Measure a packed one before you choose the postage, and check Royal Mail’s current size guide.
Kit for this step
Paper mailing bags cost roughly twice as much per bag and suit clothing and soft goods. They tear more easily when wet, so tape the seal well.
Many buyers like them, and some mention it in reviews. If your shop leans sustainable, the extra cost is often worth it.
Kit for this step
Buy the two or three sizes you use most and skip the rest. A drawer of odd sizes slows packing more than it saves.
Reorder when you open the last pack, not when it runs out. Mailers take a few days to arrive and you will not want to pause sales.
Grey plastic mailing bags for most clothing. They are light and waterproof, and cost pennies each.
Usually. A C6 board-backed mailer with a sleeved, top-loaded card is well inside the 353 × 250 × 25 mm, 750 g Large Letter limits.
No. They stop scuffs and small knocks. Anything that can crack needs a box with padding.
Most are made for kerbside paper recycling. Check the maker’s details on the pack.
Fold a typical item and measure it. Most clothing sellers stock two sizes: one for tops, one for jeans and knitwear.
