I'm interested in the '切り文字表札' (Cut-out Letter Nameplates) series. What material is primarily used for these nameplates, and what is the typical processing method for the characters? Also, if I need to make a design change after placing an order, what is the policy regarding design changes and when is the deadline for such requests?

The agent states that '切り文字表札' primarily uses 'ステンレス' (stainless steel) as the material. The agent states that the characters are typically processed using 'レーザーカット' (laser cut). The agent states that design changes are possible but only 'レイアウト承認前' (before layout approval). The agent states that changes '承認後の変更はできません' (cannot be made after approval).
