Storage box:

The storage box, nicknamed the antique box, was used by the archaeological team to store unearthed cultural relics in the early days. These boxes are generally numbered strictly, big or small, but most of them are the size of shoe boxes (unearthed cultural relics are generally heavy, and the size of shoe boxes is the most suitable for handling). In modern society, the storage box has gradually evolved into a box similar to the "sundry box", which contains things.

Storage boxes have become very common in the market. Because of its low cost and wide benefits, it is very suitable for the public to use, so there are many brands of storage boxes on the market.

Their main materials are: plastic, non-woven fabric and non-woven fabric coating. Their shortcomings are: plastic materials are easy to crack and scratch in dry climate, non-woven materials are not easy to scrub dirty, and the best is non-woven film-coated materials, which are both beautiful and easy to scrub dirty.
