All wallets have 4 pouches made from strong material. Specials can be made upon request.
The small wallet has 2.5 x 2.5 inch usable space and is perfectly sized for trout leader, furled leader and similar. Wrapping the leader around 3 fingers gives a perfect size wrap.
The medium wallet has 3 x 3.5 inch usable space. I use it for standard mono or poly leaders. Wrapping the poly leader around 4 fingers makes them fit perfectly in the pouch.
