10 day vacation feeder for fish

Wardley 10 day vacation fish feeder. 1 shell will feed a 10 gallon tank of fish for approximately 10 days. Great for keeping fish alive, and water clear while away. You will receive 5 unbroken shells in plain box. First picture is to confirm 10 day shell shape ONLY. I purchased these in bulk about 3 months ago. Unfortunately, I can no longer breed fish. 5 shells are approx 4 oz. Can bundle larger orders, or discount broken bits. Please message seller for more information. excellent for everyday use. excellent materials and excellent craftsmanship ensure long-lasting durability.
