Initially I used the parts for the electric work in boxes as they were bought but I was bulky and troubled. This product is very durable and we can arrange the product cleanly and it is handy. I also want to buy the same thing as the number of members increases.
Because the bottom of the resin tray is round, even fine parts can be taken out without catching on the corner of the bottom. Also you can remove the tray, replace the contents and rearrangement is also easy. Since there are also differences in tray size and tray single item sale, we buy more than one and use it as a preference.
