Tuck end boxes: reverse and straight.

The classic retail carton for skincare, cosmetics and small products. Here's how tuck end boxes close, the difference between reverse and straight tuck, and when to choose a stronger base.

The short answer

A tuck end box is a folding carton that closes with a flap at each end that tucks into the box. On a reverse tuck end (RTE) box, the top flap tucks in from the back and the bottom flap from the front. On a straight tuck end (STE) box, both flaps tuck in from the same side. Tuck end boxes suit light products like serums, lipsticks, creams and small accessories. We make custom printed reverse tuck end boxes in 285gsm paperboard, offset printed, from 250 units, typically 10–15 business days from artwork approval. Special finishes may take longer and are confirmed with your quote.

How a tuck end box works

A tuck end box is cut and creased from one sheet of paperboard and glued along one side seam, so it arrives flat. To use it, you open it into a tube, fold in the dust flaps at one end, then tuck the end flap in. Fill it, then close the other end the same way.

The tuck flap has a curved tongue that slides inside the box, and small "friction locks" on the dust flaps help hold it shut. That makes the box quick to pack by hand and easy for the customer to open and close.

When a tuck end box is the right choice

  • Light products. Tuck end bases hold well for light items such as serums, lip products, small jars and accessories.
  • Retail shelves. Six printable sides give plenty of room for branding, product information and barcodes.
  • Hand packing. Simple to fold and fill, and the box stores flat until you need it.

If your product is heavier, such as a glass jar or a bottle with weight to it, consider a snap lock or crash lock base, which supports more weight than a tuck flap.

Start-up · under 100 units

If you're not ready for 250 custom cartons, start with stock paperboard boxes and a custom label. When you're ready, order a single full custom printed sample before your first run.

Our cosmetic carton sample is $100, reimbursed if you order within 3 months.

Growing · 100 to 2,499 units

A printed tuck end carton is often the first retail packaging a skincare or cosmetics brand orders. Settle your product sizes first so one carton size can cover several products.

Try this: check every carton against your product's widest point, including pumps and caps.

Enterprise · 2,500 units and more

Specify the carton size, board, print, finish and closure style in your packaging specification, so every reorder matches. Offset printing on paperboard suits longer runs.

Ask about gloss or matt lamination, foil, embossing or spot UV for premium lines.

Common mistakes

  1. 1
    Using a tuck base for heavy products. A heavy jar can push the bottom flap open. Use a snap lock or crash lock base.
  2. 2
    A carton that's too loose. Products rattle and the box looks underfilled. Size the carton to the product.
  3. 3
    Forgetting the inside. Paperboard cartons can be printed inside and outside, which is a simple way to add a message.
  4. 4
    Not ordering a sample. A printed sample shows the colours, size and fit before you commit to the full run.
