I received 4 boxes, wow! Very heavy so be prepared to help your mail man get them off the truck. Delivery was super fast btw, thumbs up for Wayfair, as always they kept me in the loop, with email, texts! I did the inventory to assure all pieces are delivered. Each box has all the pieces that are needed to be in them and each pieces is meticulously labeled, thumbs up to this Company ! However it could be very intimidating, it's literally hundreds of pieces...I was able to follow along a manual to ensure all pieces are in each of the 4 boxes.. it was a daunting task but with patient and good organization it is do-able within 1 h. I found a pair of gloves in box 1 , which are so USEFUL! , since the raw corners and edges can really be painful on repeat handling without any hand protection. The "Resin" is a hollow tubed plastic board about 1/2 inch thick. Very impressed with the quality i must say. The color seems darker grey than on the photo in the sale post. I will need about a week Wayfair to start the built and i will come back and add to the review. But i must say so fare I am very impressed and give it 5 Stars. Also we are not afraid to built in the cold! So stay tuned for the finished shed! Update 12/7 we stated to built it and it's good so fare, but be aware HERE ARE NO PREDRILLED OR PRE MARKED HOLES! YOU HAVE TO MEASURE WHERE TO PUT THE SCREWS ETC. ITS NOT FOR BEGINNER BUILDERS AND IT IS ALL IN CM not INCHES.....We put 2 walls up and also the wall with the window in it, which was marked wrong on the Instructions, but as said for an advanced experienced builder it was clear to NOT go by the instructions....Anyway the quality is good , but it is a process to built due to above given reasons..
