A custom quote is a proposed specification and price, not permission to start making something. Before accepting one, make sure the description identifies the exact piece, the options being priced and the questions still open.
Start with one identifiable piece
Use a product name or a link to the listing. For example, the Angel Collar listing offers custom sizing after inquiry. That is a useful starting point for a sizing question; it does not confirm every material, closure or adjustment option.
Describe the change you want separately from the base design. If you send a reference image, explain which detail matters. Crop away identifying information that is not needed to understand the request.
Measurements need units and a direction
Write which dimension each number describes and include its unit. Ask how the studio wants a measurement taken before treating a number as the finished specification. A body measurement, a usable adjustment range and an overall product length are different pieces of information.
Keep the selected finish, hardware and set contents explicit. Mark an undecided detail as undecided rather than allowing a reference photograph to stand in for an answer.
Check what the total covers
Ask which pieces and options are included in the quoted price, which currency applies and how delivery will be calculated. Review the final checkout total before paying. Our shipping page explains the published delivery terms; it is not a guarantee that every destination or custom request is available.
Production timing and delivery timing are separate. If a date matters, identify it in the inquiry and ask what can actually be confirmed. Do not infer an arrival date from an estimate for completing the piece.
Keep the accepted version together
Use the custom quote page to send a focused inquiry. When details change, ask for an updated summary before agreeing. Keep the product reference, dimensions, options, total and timing together so that an earlier message cannot be mistaken for the current order.
A clear quote leaves fewer things to guess. An unanswered question belongs in the inquiry, not in the finished order.
