An umbrella costs 1000 Yen ($10.75 € 8.06).
I bought the following umbrella for 700 yen. It was a discount price.
The cheapest umbrella costs 105 yen (one-tenth of the above). But those are broken down easily.
A brush for floor cleaning costs 497 yen ($5.34 € 4.01) .
A wire-brush costs 140 yen ($1.51 € 1.13).
The brush is made of steel. It is for removing rust.
