3 types of kenzan that can be selected according to each situation

We have 3 types of kenzan depending on the type of bird and the situation. As a countermeasure against pigeons, starlings, crows, bulbuls, egrets, black-tailed gulls, and seagulls, you can choose the type that suits you best. Both are made of weather-resistant plastic that has cleared outdoor weather resistance tests for 10 years. In addition, a cover type with a special structure is convenient for a pipe-shaped place.

Anti-chokenzan "Type 1" For measures against pigeons, starlings, and brown-eared bulbuls. "Type 1" with a needle length of 10 cm is a standard type with excellent cost performance for preventive use.
