As I mentioned in the explanation, holes are not open. So you can drill according to your use, but because it is rubber, drilling is a bit difficult. For those who can customize themselves, is it good to work as you like?

It is extremely durable, it does not harden even if it is used for a long time, and it is hard to break. We also used similar products from other companies, but Mitsui Rubber says it will last just like hundreds of yen higher! I was surprised at it. Thank you for a nice item.

Suction work
From Japan

Although it is not drilled, it will take time and effort for processing. By being able to drill a hole with an arbitrary warp, it can be fitted to the pipe or tube to be connected and it is possible to keep the suction power without waste.

Rubber repulsion weak. Rubber deteriorates and there are countless small cracks. Not a product that seems to be considerably old inventory period and can be sold.

Although it is very good with a solid product, I think it is a bit difficult to open a hole, afterwards, although it is durable, I do not know if I do not use it in the future, but because it is easy to use next time I also would like to continue to purchase.

Since there is no hole, it is a minus one point but as a thing, it is strong, it is firm and we buy the next one.
