That's a significant upgrade for the Kaweco Profi 2! The addition of a color selector is a great customization feature that allows users to choose a color that suits their preferences or matches their farming equipment. Increasing the capacity from 20,000L to 80,000L means you can handle larger volumes of materials, reducing the need for frequent refills and increasing efficiency. Additionally, the boost in working speed from 16 to 20 km/h will help you cover more ground in less time, ultimately improving productivity during your field work. These enhancements make the Kaweco Profi 2 a more versatile and efficient tool for your agricultural activities.
