    • Thin-walled but serviceable
Color: White Size: 9x7x5-30 Boxes
These are nice boxes. The cardboard walls are thin but seem adequate. They are white so appear a bit classier than regular cardboard boxes. The size is described accurately. They are a good value for the price.

    • Just a box...
Color: White Size: 9x6x4-25 Boxes
Nice boxes, perfect for shipping an article of clothing (possibly 2). Unsure just yet of the durability of the boxes when delivered (Houston will be its 1st test from FL). Boxes are made of thin material. Made in China (? 😒).

Pros: They are nice boxes arrived in excellent condition. The shipping weight for the size will help with the overall weight and aren't too heavy. They are also cut evenly and should fold nicely to line up. They do seem sturdy but the Cons: also have some issues with the thickness of them. I will be testing them out shortly for shipping soon I believe and will add on to the review when I use them. I think they will hold up but if the take a heavy hit I don't think it would be good. The brown box is a standard Pen and Gear 6x6x6 box and the white one is the purchased item. Thickness is slightly thinner. ... show more
