I purchased this on Mercari and have used it for about 3 years. The door lock requires a bit of a push to close. The previous owner said it was like this from the beginning, so it seems to be the original specification. All parts are included. No box or instruction manual. Assembly is very easy. No pets, no smokers. Shipping will be a simple package, bundled with string and covered in plastic. Color: Gray, White Type: Baby playpen
