Review on 200-Piece Muzerdo Spring Assortment Set: Zinc Plated Compression & Extension Springs by Shane Jenkins

They are very light. Like a useless lightweight. You won't find anything like this in a hardware store. A decent range of sizes so I at least know what to look for at a hardware store. They come in a Revain case. Which, as usual, means the plastic box they were supposed to be in was cracked and broken and the quills just sat on the bottom of the envelope, all a mess. I found 2 sizes I needed, threw the rest of the envelope and feathers in the trash.
