DL size cards

Like other card sizes, DL size cards can be given to loved ones to mark special occasions such as birthdays, Christmas or other holidays. They fit handily in standard DL size envelopes.

DL size notepads

Keep on top of your tasks in and out of work with a DL size notepad, which you can use as a to-do list. The long, slim pages will mean you can keep a tidy log of your daily chores and actions.

DL size envelopes

DL size envelopes are one of the most popular types.  They’re most commonly used to send business letters, as they’re made to fit A4 paper that’s been folded into thirds. DL size envelopes actually measure larger than the standard DL size, so that DL paper can fit comfortable within it.

DL size NCR pad

NCR pads are technically not classed as DL, but measuring at 210 x 105mmm they’re very similar. Commonly used for receipts, invoices or contracts, NCR pads duplicate anything writen on the top sheet so you can keep important records without scanning or photocopying. NCR stands for No Carbon Required.
