Dear Ms, Mr, Being a Swiss company selling bank notes and coins counting machines, we are interested in products such as yours. As we need enough air pressure to be able to clean our machine from dust correctly, before purchasing could you send us sample, please? If we purchase, is it possible having our own cover on bottles (we would give you picture of it)? What would be your conditions to ship to Switzerland 7500 units, please? Thank you in advance for your reply. Best regards Matthieu Hirschi Show More
