This tray and lid set are set up so that the lid can be slide on the top or bottom of the tray. So, you can store the lid out of the way while using the tray. And then place it on the top when it's not in use or when you want to pour the contents out.
The set fits nicely into @justxkyle_274778 Diamond Art Storage Shelf, in case you are working with multiple colors at one time.
The author marked this model as their own original creation.
