I am in need of toothpaste tubes in either a 30 mL or 20 mL size with screw on caps included. The nozzle on each of these is very important and needs to be about 10 or 11 mm in diameter with a hole of about 5-6 mm in diameter. If you have any tubes meeting these requirements, I would be very interested in receiving samples and pricing from you immediately. If these tubes work and the pricing is right, I will be ordering a large amount immediately. Thanks in advance for your help! Country:USA
