For dust and insect repellent on the table. I found a goods called "dining table cover" at Daiso, a 100-yen shop.
A cover with an umbrella-like structure without a handle. If you open the skeleton a little and then pull up the string in the center of the upper part, it will spread out in all directions and become a dome shape. The size when unfolded differs depending on the product, and the two products I purchased were "about 31 x 31 x 20 cm" and "about 30 x 30 x 18 cm".
It can be a hassle to wrap each plate individually. With this table cover that can be covered widely just by opening it, it seems that you can easily take measures to prevent dust. There are various cute patterns, so why not decorate your dining table with your favorite design? Of course, the price is 108 yen (tax included).
