Turquoise in colour. Bought from Amazon.
(Description: Compatibility: this replacement strap is designed for Fitbit Charge 4/Charge 3/Charge 3 SE. NOT compatible with Fitbit Charge 2/Charge 5. (the Charge 3 device is not included).)
Size small. A bit discoloured with wear as it is a pale colour but works. Might be handy as a spare or replacement.
