一箱の大きさは24in ×15in ×12in 重さは50ポンド以下です
I think I will send about 10 boxes a month by courier to your warehouse.
Each box size is 24in ×15in ×12in, weighs under 50 pounds.
Each box is quite small and the space required will be small.
If they sell more than the initial estimate, the amount of shipment may double or three times more than the first volume. However, for the time being I am hoping I can increase the sale gradually without trying too hard.
We would ship 10 cartons per month to your warehouse by the courier service.
The carton size is 24*15*12(in), weight is under 50 pounds. You do not need to prepare large space for storage, since each carton is not so big.
In current situation, we think that we do not need to increase the quantity of the items right now.
If the sales increased beyond our expectation, the quantity would grow to 2 or 3 times, but we just want to see how the situation develop.
