Double Dragon 60 Mixed Size Self-Seal Mailer Bags | Tamper-Proof Plastic Packaging for Mailing, Postage, Shipping & Delivery | Grey (4 Sizes | Small to Large | 15 Each)

I’m really pleased with these sealable bags. I use them for my Vinted orders and they work perfectly. The grey colour looks clean and professional, which makes parcels look much more presentable when sending items to buyers. The adhesive seal is strong and keeps the package securely closed, so I feel confident that the contents stay protected during delivery. They’re also lightweight but still durable enough to handle postage without tearing easily. They’re a great size for packaging clothes and other small items, and they make the whole packing process quick and simple. I just place the item inside, peel the strip, and seal the bag. Delivery was fast and the bags arrived well packed. Overall, they’re practical, reliable, and great value for money. I’d definitely recommend them for anyone sending parcels or selling on Vinted.

Perfect for sending parcels. Come in a variety of sizes. They are slightly on the thin side but still strong enough to do the job.

I’m overall very happy with these Double Dragon self-seal mailer bags. The mixed-size pack is especially convenient—having four different sizes on hand makes it easy to choose the right bag for different items without wasting space or materials. The plastic feels thick and durable, and the tamper-proof self-seal is strong and secure, which gives peace of mind when shipping. The grey color looks professional and keeps the contents discreet. They’ve held up well during mailing and delivery with no tears or damage so far. The only minor downside is that once sealed, they’re definitely not reusable, and a couple of the bags took a bit of pressure to fully close. Overall, these are dependable, good-quality mailer bags that do exactly what they’re supposed to do. Great value for small businesses or frequent shippers—just a little room for improvement to make them perfect.

Great package. All the sizes needed. Very strong. All good :)

Great selection of sizes, use these to package up Vinted sales and they are nice and thick to keep things safe.

Nice variety of sizes. Not the thickest but double up if needed. Sellotape doesnt stick to it very well. Self stick strip to close bag is good. Overall not bad for price.

I bought the Double Dragon 100-Pack in 4 sizes (4x9, 9x12, 10x14) specifically for shipping items sold on Vinted, and they’ve been exactly what I needed. The size variety is the biggest plus—it makes it easy to choose the right envelope without wasting space or needing extra padding. The material feels durable enough for mailing clothing and small items, and the adhesive seals securely, which is important when sending orders through the post. I’ve used several packs so far, and they’ve held up well during shipping with no tearing or opening issues. Having multiple sizes in one pack is especially convenient if you sell different types of items. A simple, reliable packaging solution for online sellers. If you ship Vinted orders (or similar resale platforms), this pack is practical, good value, and does the job without issues.

I purchased the Double Dragon 60 Mixed Size Self Seal Mailer Bags pack for small business shipping, and they’ve been excellent value. The variety of four sizes (15 of each) is really practical perfect for sending everything from small accessories to larger clothing items. The self-seal strip is strong and secure, giving a clear tamper proof closure that doesn’t peel open during transit. The plastic is durable and tear resistant without being overly thick or bulky. They’re lightweight, waterproof, and professional-looking, which helps keep postage costs down while protecting items properly. A reliable, cost-effective choice for regular mailing and online sellers.

Ho acquistato queste buste in plastica con chiusura adesiva in tre diverse misure e sono rimasto/a molto soddisfatto/a. La plastica non è trasparente e di buona qualità, abbastanza resistente per contenere oggetti senza rischio di strappi. La chiusura adesiva è pratica e tiene bene, permettendo una sigillatura rapida e ordinata. Le tre misure sono molto utili perché consentono di adattare la busta a diversi tipi di oggetti, evitando sprechi di spazio. Ottime per imballaggi, spedizioni, regali o organizzazione, risultano versatili e facili da usare. Buon rapporto qualità-prezzo. Consigliate.

Superbra fraktpåsar till kanonpris!

Really nice to sell and ship my packages or returns with.

Good sturdy bags but 4 sizes is not true, there are only 3 sizes of bags.

Good assortment of sizes. Sturdy enough.
