これは非常に難しい問題です.....
あなたも理解していると思いますが、
ドラムスティックは木製品なので、耐久性にバラツキがあります。
スティックは数分で折れてしまう物もあれば、最後まで折れずに使用できる物もあります。
以上の理由から、
ドラムスティックは消耗品の為、ドラムメーカーは保証を付けていません。
当店からあなたへ相談があります。
あなたの息子さんの為に、
特別にドラムスティックを一本だけ無料で交換させていただけますか?
しかし、送料の6.00ドルだけ支払いをお願いできますか?
As you are aware, the drum stick is made of wood so its durability varies.
Some may break in a few minutes and others will remain useable without a break till the end.
Due to the above reason, the drum sticks are deemed to be expendable, they do not come with a warranty.
Here is our proposal for you.
For the sake of your son, as a special case, may we replace a single drum stick at no cost?
However, may we ask you to pay for $6,00 shipping fee?
I think you also understand,
drumsticks is made by wood, therefore there is a variation in durability.
Some of them break in a few minutes, and some of them can be used until the end without breaking.
For the above reason,
drum manufactures don't offer a warranty because the drumsticks are consumable goods.
Our store has something we would like to ask you about.
Is it possible to exchange one drumstick for free only for your son?
However, could you please make a payment for shipping fee of 6.00 dollars?
As you probably understand, the drumsticks are made of wood therefore the durability depends. The stick sometimes last only one time use or last longer.
For the reason, the drumsticks are the expendable supplies,and it has no guarantee by manufacturer.
I have a talk to you. As a gesture of our courtesy, at this time we will offer you a drumstick for free. But can I ask you paying just 6 dollars for shipping charge?
