The finishing layer every XL or XXL tray is designed around. Each liner sits between the tray and the grass, absorbing moisture and catching mess so the tray itself stays clean — no scrubbing, no staining, no wear, no matter which tray you own.

When it’s time for fresh grass, roll up the old grass and liner together and discard them. Add a fresh liner, place the new grass on top, and you’re all set. Use one liner for an XL tray or two for an XXL.
