We want you to be 100% satisfied with any order placed with us. Therefore if you are dissatisfied with your purchase and wish to return an item you may contact us by email at sales@lilpackaging.com within 30 days of your purchase, stating the reason for return*. We will then supply you with a return address and returns number, which is very important, because no goods can be returned without a returns number.

Goods can be returned for a full refund only if they are faulty or if we've dispatched the wrong items.

*If the correct goods have been sent and you've made a mistake whilst placing the order, we are happy to accept returns for a refund, but you will need to cover delivery costs.

Nothing in these conditions affects your statutory rights as a consumer. The credit card or PayPal account used for the purchase will be credited with the original purchase amount (less any delivery charge paid where appropriate).

In the unlikely event of your custom packaging arriving damaged, missing items or is of incorrect specification (outside of the print, material specifications and variances as stated on our product descriptions) then please contact our mail happy team on sales@lilpackaging.com who will be more than happy to help you put things right.

As these items are made to order, we can only offer returns if the items you purchased are deemed faulty.

    Plastic free corrugated cardboard envelope!

    Indestructible Cardboard Envelope

    Fits A4 brochures, calendars, DVDs, photos, photo frames and more

    Description

    Looking for a large letter envelope to maximise the Royal Mail large letter size limit of 353 x 250 x 25mm? The Lil A3 is a large letter mailer featuring our cardboard envelope range. This mailer is perfect for delivering A4 brochures, calendars, DVDs, photos, photo frames and more through the postal system. With its attractive 'kraft' finish, customers will open this effective packaging to receive their products in the condition in which they ordered them. The A3 large letter envelopes are made from very stiff 450 gsm material with specially designed folds to provide impact protection around the edges minimising the risk of impact damage. The envelope features our leading peel'n'seal / tear-strip system for easy sealing and opening. See our other Corrugated Cardboard Envelopes.

    All products within our envelope range are made from 100% recycled material and are 100% recyclable. The Lil envelopes are the most eco-friendly, plastic free alternative to a standard padded envelope or bubble mailer and they represent a significant step forward in the removal of single use plastics from ecommerce packaging. Eco-friendly padded envelopes that are stuffed with post consumer recycled fibre actually use MORE material than our envelopes and are considerably slower to pack, yet they don't provide any additional protection or cost savings. This is why our envelopes are trusted to deliver products and media across the globe by the internet's biggest online retailer.

    AusPost and Royal Mail Large Letter envelope maximiser for cheap postal tariff mailings. Our sizes are extensively researched to get the snuggest fit and lowest cost mailing tariff.

    This range was co-developed with one of the Internet's largest retailers... so you might recognise our envelopes!

    This Lil envelope is incredibly stiff, yet a total product thickness of only 1.71mm means that you can send items up to 23mm thick through the large letter price tariff. A standard 6mm - 8mm thick bubble mailer would fail in this regard. This results in a potential £2 saved, per item mailed. Tired of returns and unhappy customers? These envelopes are better than bubble mailers; the corner stiffness of the A3 envelope cuts damage in transit. Online retailers report nearly 70% fewer returns and 25% faster packing. Struggling with storage space for your packaging? The easy stack design of the A3 envelope is the answer.


    Your packaging is the first time that your customer will physically experience your product. Getting it right is your chance to make the best first impression. We help you do just that with our award winning range of Lil envelopes. This brilliant, tough envelope is one of our best selling items for a reason. If you're looking for sturdy and cost effective packaging for mailing A4 brochures, calendars, DVDs, photo frames and more consider nothing else, (don't use cheap envelopes that fall apart, leave your items damaged and your customers dissatisfied). Go on...burst that bubble!

    Great packaging

    So impressed, the packaging is great and no plastic- hurrah! Shame the postage for 2 samples was £8, bit steep really but you’re forgiven because they were so good 👍

    Great service and products

    M2 Envelopes

    Bought as they were the cheapest available, however the cardboard on these is very soft unlike the hard type of cardboard used on the M2 envelopes we use.

    A194+ ...

    A good product but it is a pity that they are not available in smaller quantities from the manufacturer. One has to look on other platforms to see them available in smaller packs.

    Excellent Packaging

    Sturdy and perfect size . well made . Look good .
    And good for environment.
