Questions, answered.
What is the minimum order?
Minimums start at one case. Expandable mailers and refrigerants sell by the case, stock box liners by the pallet, and recycled PET mailers are quoted. Every product page lists its minimum.
How fast will I get a quote?
Standard quotes go out within 1 business day; custom sizes and non-stock items can take longer, and we tell you when to expect them. Every quote states the lead time for your SKUs and quantity in writing before you commit.
Is your packaging validated?
Yes. Our mailers are ISTA 7E validated, and each product page lists the configuration that was tested. ISTA 7E validation is also available for your exact pack-out.
Why don't you list prices?
Price depends on the product, size, quantity and freight to your ZIP code, so we quote it in writing. Standard quotes come back within 1 business day; custom sizes can take longer, and we tell you when to expect them.
Is the packaging recyclable?
The recycled PET mailer and all four of our box liners are curbside recyclable. The recycled paper liner is plastic-free, made from 100% pre-consumer recycled cardboard fiber.
Where do you ship from?
From 13 warehouses across the continental US, within one-day ground of 96% of the US population.
We don't have warehouse space. Can you help?
Yes. We set up scheduled deliveries, multiple times a week if you need them, so you hold days of packaging and refrigerant instead of months.
