This is a greenhouse cover made of transparent vinyl. It fits perfectly on a Luminous 5-tier rack with a width of 91.5 cm and a depth of 46 cm. (There might be a small gap at the bottom if you use casters.) I purchased it for use with a panel heater, but I am also selling the panel heater and USB fan separately as I am re-evaluating my breeding scale. I purchased it on October 25th, so it has not been used for even 3 months. However, since the product originally came compactly packed in a small dedicated bag, there are wrinkles. As the condition is almost unchanged from when I purchased it, I have listed the condition as "No noticeable scratches or dirt," but please refer to the images if you are concerned. (No claims, no returns, please.) - Model Name: TOP-RC174 - Size: Outer dimensions approx. 92 x 46.5 x 174.5 cm - Material: Transparent vinyl - Use: Greenhouse/Breeding case - Accessories: None (Negotiable for bundled sale with separately listed panel heater and USB fan) As I am also listing this item elsewhere, please send me a message in advance if you wish to purchase it. Thank you for looking.
