Read Receipt Bookmarks are a new kind of collection for the book lover: one bookmark for every book you finish.

It's a play on the digital read receipt. That one proves you've seen a text message. This one proves you finished Middlemarch.

When you reach the last page, there are a few questions to fill in: the date, what stayed with you, your verdict. Keep each one, and slowly you build a record of the books you made it to the end of. A serious achievement in our age of distraction.

Six colours, each with their own prompts, and a wine-coloured tassel to gather them on, a nod to the dark, cosy corners of an old library. The more you read, the more beautiful your collection becomes - which is quite the incentive to finish the book.

You've turned the last page. Now keep the receipt.
