## Questions & Answers

**Q: Are these needles compatible with Lantus pen?**
A: Those needles work ok with the Lantis pen but the quality is not as good as B&D.But at the price B&D charges I will use MedFine needles.Good Luck

**Q: Do these needles twist on the lantus pen**
A: Yes they do.  I used them on lantus & they work fine.

**Q: what is the difference in 5mm and 8mm**
A: 5mm have shorter needle penetration length than 8mm.  They may be advertised as finer.  I've used both, I don't like the 5mm as much as the longer 8mm because for me the 5mm seem to hurt when injecting the insulin more than the longer 8mm ones.

**Q: I have ordered this items many times before but now I get a message that it cannot be shipped to my home address.  Has anybody had the same issue?**
A: Hi Joel,
We first noticed this "restriction" put up by Amazon on 12/11/2020 morning. 
Amazon is the one to put the "restriction" on ALL pen needles sales. 
We did NOT put those "restriction" on the Amazon website. 

We already contact Amazon and ask them to remove those “restriction”. 
However, this is the only response from Amazon: 

"This product has been identified as an insulin pen, needle, or similar insulin device product that that is subject to regulation in the states of California, Connecticut, Delaware, District of Columbia, Georgia, Guam, Illinois, Indiana, Massachusetts, Minnesota, Nevada, New Hampshire, New Jersey, New York, Oklahoma, Puerto Rico, Rhode Island, South Carolina, Tennessee, and Virginia. Although permissible for listing on Amazon, such products cannot be sold into the above states based on state law and Amazon policy."

We believe our products are medical equipment, not medicine. 
We don't think you need prescription to purchase our products. 
We believe Amazon put us in the wrong category. 
Therefore, we are asking Amazon to do a further review of our products. 

Customers called us and told us that when they called Amazon, Amazon told them we are the one put the "restriction". 
This is not true! 
Amazon is the party who put the "restriction" on all pen needle products, NOT us! 

We are trying our best to resolve this issue with Amazon. 
But it takes times for Amazon to come to their sense. 

Currently, we have plenty of inventory at Amazon Warehouse. 
It just that Amazon are blocking the sales to certain States for the above reason.

We are waiting for Amazon to reverse their decision, if possible. 
You can also contact Amazon to let them know these pen needles doesn't require any prescription to purchase. 
Amazon should not limit the sales of pen needle to certain States only. 

Short term solution for your reference : 
We got a phone call from a customer.
Because she is in SC, so she can't purchase the needle direct from Amazon.
But she mentioned that she will ask her friend in MD, which is not on the "restricted list", to purchase for her.
Then her friend can send the needle to her in SC.
I guess this is the short-term solution for now.
Also, most of our needle now have shelf life until 2025.
So you might want to buy some extra boxes if you don't want to bother your friend too often.

At the same time, please check back on the Amazon website regularly to find out if there is any changes

We are very sorry about the inconvenience. 

Thanks!
