Getting custom boxes means you must find a right manufacturer within your radar so that you get your box designed. The benefit of your custom boxes will be apparent from the design process. However, here are a few points you should consider before choosing a custom box manufacturer:

•    Place: You must find a manufacturer close to your place as it is beneficial because you can see the way boxes are made and in this way being close implies you can save on the freight and shipping costs.
•    Fulfilment: Manufacturers provide fulfilment solutions. If you work with such manufacturers, your custom boxes production and fulfilment helps as it removes the freight or shipping costs on the boxes as both are under the same umbrella. 
•    Price: Asking for quotes means you must mention the specific size and keep in mind the order quantity. You may compare the manufacturers based on the price, but be cautious about manufacturers who offer much low prices. This is because they may be reducing the outer and inner liner. A thinner liner means you can easily see the little rivets of the box. Having a better liner is essential to have better printing quality on the boxes.
•    Turnaround time: It takes 3-4 weeks to get the tools such as dies and plates created for any box order. You may include to this another 1-2 weeks of shipping your order if you have chosen a manufacturer away from your place. However, keep the turnaround time in your mind as calculation and speak to the manufacturers.
