B2B Frequently Asked Questions
Q1: What lead time should we plan for on square black instant?
A: Lead time runs from sample approval. Where an existing mould suits the specification the run follows quickly; where new tooling is needed, we schedule it into the next available slot and confirm the date in writing.
Q2: Which sizes are available across this range?
A: The range runs in graded sizes sharing a common rim dimension, so one shelf or line configuration covers several formats without separate tooling.
Q3: Is the colour consistent from batch to batch?
A: Colour is matched to a retained standard and checked at start-up and through the run, so batch-to-batch variation stays inside a tight tolerance band.
