Caring for your caddy.
It is cardboard. Do not get it wet. Beyond that, it lasts.
Keep it dry
Kraft cardboard handles surface moisture but not soaking. If it gets wet, air-dry flat. Replacement caddies are available as refill items at low cost.
Foam insert
The 1/4 inch EVA insert can be wiped clean with a damp cloth. It is the same foam used in shoe insoles.
When to replace
The cardboard caddy is rated for at least 200 open-close cycles, which is roughly one a day for 7 months. Most golfers replace once a year with a refill order.
