Why sellers choose iSOUL Grey parcel bags
- Strong 60 micron film: thick enough to resist tearing in transit, yet light to keep postage costs down.
- 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: Grey 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, shoes in soft packaging, accessories and other soft goods that don't need a box.
- Eye-catching colour: bright Grey parcels stand out and look more professional and memorable than plain grey bags.
- Bulk packs save money: choose 100, 200, 500 or 1000 bags – the bigger the pack, the lower the cost per bag.
- Works with all couriers: Royal Mail, Evri, DPD, Yodel, InPost and Vinted drop-off points.
Frequently asked questions
What's the difference between mailing bags and parcel bags?
None – they're the same thing. Mailing bags, parcel bags, postage bags, postal bags, and poly mailers are all names for self-seal plastic bags used to post items.
What size parcel bag do I need for Vinted?
Most Vinted sellers use 10 x 14" for everyday clothing like dresses and jeans, 9 x 12" for T-shirts and tops, and 12 x 16" or larger for jumpers and coats.
Are these parcel bags good for posting clothes?
Yes. Clothing is what most of our customers post in them – they're strong, light, and keep garments clean and dry.
Can I send these as a Royal Mail Large Letter?
The 6 x 9" and 9 x 12" bags can be used, as long as the packed parcel stays within Royal Mail's Large Letter limits (353 x 250 x 25 mm, up to 750 g). Please check Royal Mail's current size rules before posting.
Are the bags see-through?
No. They're fully opaque with a black inner layer, so contents stay private.
Can I reopen and reseal them?
No. The seal is permanent for security, which keeps your parcel tamper-evident.
Are they waterproof?
They're water-resistant and protect contents from rain and dirt in transit.
Can I write on them or use labels?
Yes. Shipping labels stick well, and you can write on them with a permanent marker.
Is delivery free?
Yes, UK delivery is free on all orders, with no minimum spend.

I've tried loads of different mailing bags and these are the best by some distance. The polythene is noticeably thicker and the seal is rock solid. Perfect for my eBay business.
Thank you
Ordered these for my small online shop and they've been a game changer. The slate grey colour looks really professional and the waterproof material keeps everything dry. Will reorder without hesitation.
Thank you
These are by far the best parcel bags I've used. Thick, sturdy and the seal never fails. I send clothes and accessories regularly and not a single bag has split or leaked.
Thank you
Ordered these to replace my old flimsy bags and the difference is night and day. Much thicker plastic, much stronger seal. Perfect for sending cosmetics and accessories.
Thank you
Happy with these bags. They're well made, waterproof and the self-seal strip is strong. The grey colour is smart. Only minus is they could be a touch thicker, but they do the job well.
Thank you
These are now my go-to mailing bags. The slate grey is professional and understated and the self-seal strip grips brilliantly. Great for small items and larger clothing bundles alike.
Thank you
Used these for sending books and they worked perfectly. No damage at all and the seal stayed firmly shut throughout. The grey looks great too — very professional.
Thank you
Great for small business use. I order in bulk and the price per bag is excellent. Quality is consistent across every pack I've ordered. The waterproof coating is brilliant.
Thank you
These grey postal bags are superb quality. I use them for my clothing resale business and every single parcel arrives safely. The tamper-proof seal is a real selling point for my customers.
Thank you
Happy with these bags. They're well made, waterproof and the self-seal strip is strong. The grey colour is smart. Only minus is they could be a touch thicker, but they do the job well.

Thank you
Fantastic value. The grey is a lovely shade — not too dark, not too light — and the material is thick and durable. No complaints at all. Will be ordering again very soon.
Thank you
Ordered these to replace my old flimsy bags and the difference is night and day. Much thicker plastic, much stronger seal. Perfect for sending cosmetics and accessories.
Thank you
These grey mailing bags are exactly what I was looking for. Waterproof, strong seal and a lovely dark grey colour. Much better than the cheap bags I was using before.
Thank you

Thank you
Perfect posting bags. The polythene is thick, the tamper-proof seal is reliable and the grey looks very smart. Far better than any other bags I've tried at this price point.

Thank you
These bags are really good for the price. Waterproof, decent seal and a smart grey colour. I'd give five stars but the seal on a couple of bags in my last order wasn't quite as strong.
Thank you
Not as good as expected. The grey is darker than it looked in the photos and the plastic feels cheap. The seal is very weak. Had several complaints from customers about damaged parcels.
Thank you
These are now my go-to mailing bags. The slate grey is professional and understated and the self-seal strip grips brilliantly. Great for small items and larger clothing bundles alike.
Thank you
Excellent quality throughout. The bags feel thick and substantial, the seal is secure and the grey colour gives a really professional impression. Highly satisfied with this purchase.
Thank you
Really impressed with these bags. The dark grey colour is sleek and smart-looking, and the tamper-proof seal gives me real peace of mind. Great value for the quality you get.
Thank you
These bags have transformed my packaging. They look professional, they're strong and the self-seal strip works perfectly every time. My customers always comment on how neat their orders look.
Thank you
Not recommended. The self-seal strip kept failing and I had several parcels arrive open. The grey colour was the right shade but the bags themselves are poor quality.
Thank you
Great for small business use. I order in bulk and the price per bag is excellent. Quality is consistent across every pack I've ordered. The waterproof coating is brilliant.
Thank you
These are by far the best parcel bags I've used. Thick, sturdy and the seal never fails. I send clothes and accessories regularly and not a single bag has split or leaked.
Thank you
Very happy with these. The dark grey colour is much nicer than plain white and they feel genuinely substantial. Not flimsy at all. Will definitely keep buying from this seller.
Thank you
