The Minimalist key float is just that - the minimum. This key chain is made with 2 all-natural cork balls - 1.25" and 1" in diameter.
The genuine military spec paracord goes completely through the corks and is attached to itself using a steel j clip. The split key ring is also steel - for years of continued use.
Our testing has this key float being able to float 2 keys (kw1) just below the surface in fresh water.
Our high quality key floats are handmade, on the coast in Westerly, RI - celebrating 350 years of history.
