I have purchased several of these Quartet Natural Cork Classroom Bulletin Board, 4 x 4 Feet, SureLox Hanging System and Installation Kit Included, Aluminum Frame (ECKA404) recently. The product is excellent and most definitely the best value around BUT the packaging is inferior. Make sure you open and thoroughly inspect the corkboard BEFORE receiving. I have found creases and moisture damage. Would have been 5-star if better packaging. The shipper also damaged one box. Your judgement if that is the shippers fault or the product manufacturer. If you can manage to get one undamaged the product itself is excellent, your basic corkboard for a great price!
