We’re actively collecting vendor pricing for white 3 1/8 inch square envelopes. No market data is available yet.
Submit your quoted price to help establish a benchmark.
Priced per unit; vendors typically quote against a primary quantity.
Usually a specification or finishing difference, not the core work. Ask both vendors to quote the identical spec and the gap normally narrows.
The same product family is tracked in 2.36×2.36, 9.49×7.01. Quotes are NOT interchangeable across variants, so match the spec before comparing.
