ONE-CARE Pen Tips - 31 gauge x 5 mm (3/16’’) Ultra-Thin for Comfortable Injections -Diabetes Pen Tips for Injections - Universal Fit Compatible with most injectors available on the market - Set of 100

I buy these for my cat and they work well. He is a diabetic with a thick coat. I found that other brands I tried weren't long enough to get past the fur and deliver his insulin.

Thank goodness I can purchase these pen needles from Amazon, otherwise I would go broke! They always fit, I have never encountered a defective one. The seals and needle covers are always intact. They always attach the way they are supposed. They are never dull. The quality is spot on for what you would expect from medical supplies, yet priced reasonably.

Quality Product, reasonable price

Works great and much more cost effective them going thru my pharmacy.

A lot less $ than getting these through pharmacy and putting through our insurance.

If your insurance high or doctor forgets write prescription for needles these are great value compared to some Pharmacy cost especially locally owned doesn't offer cheaper varient.My Pharmacy carries a higher end product more expensive. No difference in why they feal when inserting in your skin. Needle part is high quality only thing different is these compared to more costly brand is how tight you can screw the needle onto the pen. Higher end you can tighten down with fingers without threads slipping. These are lot easier for the threads to give & on loosen when over tighten. But it doesn't mess up the needle just tighten again just not as much. They may not be able to tighten down as tight as more quality brands but it doesn't affect functionality. I've used these to insert thick long acting insulin with no issues.

This needles are better and smaller

Highly recommended, it's way cheaper than prescribed ones and it's good quality.
