Customer Reviews

Justin Lawrence
These are the Box Bosses
Great site with lots of options and I really appreciate being able to check the pricing on each style of box. Also being able to see a 3D version of my customized box is a game changer! I will definitely be back to order more boxes.
Great customer service and product…
Great customer service and product quality so far from the samples we received and needed assistance with! Looking forward to working more with Packola in the future!
Easy to use design template
Easy to use design template. Fairly quick processing and shipping of my boxes. Checked 15 or 20 competitors, could not even find a price close to these.
Happy Customer!
The company was very responsive to my (MANY) questions and check in's on status of our order. The expedited option for production is unmatched in terms of timing and enabled us to meet our VERY fast timeline we were working against! The Mailer Boxes we had produced came out beautiful and were a nice sturdy material. 10/10 would recommend.
I’m beyond satisfied with my order
I’m beyond satisfied with my order. This is my first time starting a business and I had no clue about mailer box size and I made the wrong on the size and Packola manger stepped up and aided me tremendously by replacing my order without any problem. I'll definitely be working with them again! I will delightedly recommend Packola. Thank you so much for helping a small business owner out!

Part of a rebrand -- and the mailers look so good!
We are so pleased with how our branded mailer boxes came out. Can't wait to mail them off! This is part of a big rebrand project, so it was critical to get this right to help us make a splash. My designer was also very happy with the experience working with your production team to make sure the artwork came out perfect.

Highly Recommended
I had a very tight deadline for custom printed mailer boxes. Took a chance with these guys. Turned out to be a very good decision. Not only did they hit my almost unrealistic deadline, Adam/Packola delivered some of the best customer service I've ever experienced in my career. My boxes looked great. Price was good. The online design tool on their site is great for mockups too. I'd use them again for sure. Highly recommended.
Mary Bemis
Great customer service who answered all…
Great customer service who answered all my questions in a timely matter and the final result looks amazing - I've gotten a ton of compliments on our custom mailers! I also appreciate that they answered my further questions about what it meant to offer "sustainably sourced" materials.
Everything I could have asked for
The Packola Team was everything I could have asked for when starting my subscription box company. Their customer service is excellent, they worked with me tirelessly to make sure I was getting everything I needed, and I was very impressed with their knowledge and ability to share their knowledge with me in a way I could understand with no previous box experience. The build your box feature on the website is top of the line, and would highly recommend them to anyone with their box needs.
