Drainer net stockings

I hate cleaning the grime off, so I bought this product and was surprised to find that it was so easy to use and left the drain clean! I change it once a week. It's an item I can't do without.

The quality is better than the 100 yen store ones, so I've been using it for a long time. It's so convenient that I always have three boxes in stock, and I get worried when they run out sometimes.
