Even if you have very little medical experience-if you have a farm you MUST have these on hand. So many injuries happen after hours, and vets charge a fortune! I have used these a few times with tremendous success. It can be challenging to stitch a wound, but the results are so well worth it! They work great, are easy to use, and the wounds heal up clean and easy. Plus if you stitch deep wounds as soon as they happen you reduce the risk of infection tremendously.
