White flexible plastic, easy on, easy off. I love these new finger trays from 2GR! 2 1/8" L x 1/2" Wide - Plastic and fit 1/2" bar space cages. Simply slide thru the outside and click into place. Great supplement trays that are easily serviced from outside the cage.
Great for Eggshell and Kelp! Mixed color case is Yellow, Green and White
