Filed and sorted. Stefan wants to reorganize his contacts. The business cards he has received over the years are practical, but he also wants to note when he last had contact with a person and what projects emerged from that. He already has the index cards – they are large A5 cards, giving him plenty of space to write. But how can Stefan easily and quickly sort these index cards? This index card register from Durable can help with the organization. With a card box system (not included) and this product, not only addresses but also keywords or technical terms can be quickly filed and sorted. Thanks to the blue color, the next letter is immediately recognizable, unless your index cards are the same color.
