Review on 🔧 SP 9901 Miscellaneous by Prime Line Products by John Clark

Many different compression and extension springs as noted by other reviewers. I was pleasantly surprised by the quality at a great price. I was also surprised that there are some fairly strong compression springs (i.e. heavy/impossible to manually depress). But I was a little disappointed that there weren't heavier mainsprings. All in all a great set that will definitely come in handy.
