Very pleased with the insulin syringes for my diabetic Westie. Abbie is 14 years old and has had diabetes for over 3 years. The Terumo 1/2-inch syringe penetrates through her thick skin and administers a speedy dose of insulin, efficiently aiding in her maintenance. These syringes are individually wrapped and are always of the highest quality and sharpness. She actually looks forward to her injection (of course the little treat I offer afterward doesn't hurt either). I highly recommend this product and the price is reasonable as well.
