Review: Easy to piece together, sturdy, and looks amazing - Absolutely perfect for me for my small etsy business. I have different sized boxes for different items/quantities and this is probably my top favorite item. The size I ordered is perfect for the items intended to use it for. I pair it with black tissue paper for a nice display and throw a logo sticker on the box to finish it off. It makes a huge difference in the appearance of the products when they arrive to my customers and makes it feel more luxurious, professional, and special vs throwing items in a random mailer. The quality of the boxes are equally as amazing, they are extremely easy to put together and the sturdiness is fantastic. I will 100% recommend this product and continue to purchase again when it’s needed.
