Waterproof parts should be provided by Spare.

I would like to thank you for selling this kind of small parts.
Waterproof performance degrades over time as a matter of course; if it's in Catalogue, you should buy it.
The evaluation includes imagination and expectation because the replacement work has not been done.
Of course, there is no Instruction Manual.

Bagian tahan air harus disediakan oleh Cadangan.

Saya ingin mengucapkan terima kasih karena telah menjual suku cadang kecil semacam ini.
Kinerja kedap air menurun seiring berjalannya waktu; jika ada di Katalog, Anda harus membelinya.
Penilaiannya meliputi imajinasi dan ekspektasi karena belum dilakukannya pekerjaan pengganti.
Tentu saja, tidak ada Instruksi Manual.
