I used to replace it with a sharp instrument at the tip, but the neighborhood was scratched or stained. It is almost safe without scratches, and it comes out with a single blow. There is also a sense of stability as you can change the angle. Though inexpensive things are also sold, it will be "imitation". I have not used it, but the things that are cheap are uneasy as materials. Until now, we used a cheap tool pretty well, but when saying "speech" a sense of security is different even if it is a bit high.
I own some tools for Lyle, but the price is also cheap, simple structure, easy to use. This seal pooler can change the angle of the head, so it can be used in various situations. Many special tools are expensive, medium lilies are very easy to buy.
