In the fasteners, springs, and industrial hardware aisle, a single broken compression spring can stop a repair cold. A pen that won't click, a hinge that hangs loose, a tool that loses its return action-all of them come down to one tiny steel coil. The practical fix is an assortment kit, but these kits are not all the same: they differ in piece count, number of sizes, and how the set is organized.
Quick take
If you want a large supply for general fixes, the 390-piece kit is the easiest call: it has the most pieces and the lowest listed price. If you need to test across a wider ladder of dimensions, the 300-piece kit gives you 30 sizes for a mid-range price. The 380-piece set is aimed at tiny pen and craft-size springs, while the CREEYA 225-piece kit is the most compact option for a narrower range of mini work.

Product notes
CREEYA 225-Piece Mini Stainless Compression Springs
At $14.15, the CREEYA kit is the smallest of the four, with 15 sizes and 225 pieces, all arranged around mini dimensions: 10mm to 30mm lengths and 4mm to 6mm outer diameters. The 15-piece repeats per size are convenient when you want a small working stock of each common tiny spring rather than a deep bin of odd sizes. The stainless material fits damp or humid workshop conditions. The limitation is that this set is easy to outgrow. If your repair drawer needs to cover larger or more varied spring sizes, the 225-piece count and 15-size range will feel narrow, especially at a price that is closer to the largest kits than to the lowest-priced one.
300 Pcs Compression Springs Assortment Kit
The Ninoge kit sells for $11.93 and packs 300 pieces into 30 sizes, which is the widest size selection of the group. With 10 pieces per size, you can work through a range of spring dimensions without sacrificing all of one size on a single attempt. The set is built for shop and home repairs, and the stainless material matches the rest of the lineup's rust-resistant intentions. The catch is a middle-of-the-road piece count: 300 springs is more than the CREEYA kit but less than both the 380 and 390 kits. If your goal is max volume, you can get more pieces for less money from the 390-piece kit, so the Ninoge set is best when the size ladder matters more than the total count.
380PCS Stainless Steel Compression Springs Assortment Kit
The 380-piece stainless set is the top-priced kit at $14.99, and it targets a specific niche: small and tiny springs in 23 sizes, with wire thickness from 0.3mm to 0.7mm. That makes it a strong match for pen repair, small DIY, and workshop fixes where you need a large number of mini springs in a tight dimensional range. The 380-piece count is just below the 390-piece set, but the size range is narrower, so you are paying the most here for a kit that is more focused than it is broad. If you already know your jobs live in the small-spring zone, this set gives you plenty of spares; if you want to cover more sizes per dollar, the lower-priced kits offer that instead.
390 Piece Compression Spring Assortment Kit
The 390-piece kit is the list-price leader of the four at $10.90. It gives you the most pieces and, at 28 sizes, the widest dimension spread in this comparison, with wire diameters from 0.3mm to 0.8mm, outer diameters from 2mm to 8mm, and free lengths from 5mm to 30mm. The 304 stainless construction keeps it in line with the other kits for corrosion resistance, and the reusable compartmentalized case means the labeled sections actually make the 28 sizes easy to sort through. The limitation is that this is still a small-spring assortment, so it cannot substitute for a large industrial spring selection. For the price, it is the easiest way to get broad coverage in one box.
Final recommendation by use case
- General shop stock: The 390 Piece Compression Spring Assortment Kit. It has the highest piece count, the widest listed size range, and the lowest listed price; the compartment case is a bonus.
- Fit-finding for an unknown spring size: The 300 Pcs Compression Springs Assortment Kit. Its 30 sizes give you the most opportunities to test-match a mystery spring.
- Tiny pen and craft repairs: The 380PCS Stainless Steel Compression Springs Assortment Kit. It focuses on the smallest spring range and offers 380 pieces for high-volume small fixes.
- Known mini sizes only: The CREEYA 225-Piece Mini Stainless Compression Springs kit. Its 15-size, all-mini range keeps the drawer compact and speeds up selection.
