Choosing between flexi's ranges — Classic, Black Design, Neon, Xtreme — usually comes down to which detail matters most to you, since the core mechanism doesn't change between them.

This is the Medium size in flexi's Black Design range, a 5m tape leash rated for dogs up to 25kg, available in four colours — green, pink, blue and black. Like the Large size in the same range, it can be customised with a Multi Box or LED Lighting System.

• 5m tape leash
• For dogs up to a maximum of 25kg
• Available in green, pink, blue or black
• Comfortable braking system
• Can be customised with a Multi Box and LED Lighting System
• Product weight approximately 235g

On choosing a flexi range. Black Design, Classic, Neon and Xtreme all use broadly the same braking mechanism, so the real differences between them are cosmetic and feature-based — colour choice, reflective panels, or reinforced tape — rather than one being fundamentally stronger than another at the same weight rating.

Who it's for: an owner of a medium dog up to 25kg who likes the Black Design colour range and wants the option to add accessories like a Multi Box later.
