Box in-box

This is an application of a box in a box.

Modern people often use boxes to install things, but the size of the "box" loading the goods will cause trouble, because people often can not well estimate the storage space of the "box", the "box" loading the goods is too large or too small.

So we developed a team and developed such an application.

Using it, you can simulate the size of the "box" in advance, and then estimate the size of the space based on the graphics in the application, which can help people save a lot of time to estimate the size of the "box".
