1020 Clear Humidity Dome - Extra Strength

Does not fit the shallow trays very well. You can sit it on top and it stays, but it slides around quite a bit, 1 cm or so each side. The bigger deal is the geometry is such that water will drip down the sides and out of the tray making whatever you put the tray on wet around the outside thereby removing all the water from your tray. This could have been avoided by choosing a geometry that drips into the tray.

Great item. Works perfectly with the adjusting of the openings on top to let air in.

Its a durable humidity dome. Consider it double dipped.
