Perforated to-do lists for your Circa® notebook. Designed for those inveterate organizers with perpetually long to-do lists, this versatile Circa refill works in a variety of ways. Each sheet offers two checklists and is perforated down the middle and on the left. You can organize the lists by topic, task, date or doer’s name. Take one section with you and leave one as a record in your Circa notebook, or detach both to give instructions to two helpers (lucky you!).
