Shopping for fasteners, springs, and industrial hardware often starts with a simple question: which compression spring assortment actually covers your repair or DIY needs without leaving you hunting for a missing size? Two compression spring kits make that decision interesting: the 380PCS Compression Spring Assortment Kit from Ladinka and the 390pc Compression Spring Assortment Kit. The 380PCS option is aimed at home repairs, crafts, and DIY projects, while the 390pc kit is positioned as a workshop fix-it essential. The Ladinka set is listed at USD 10.51, while the 390pc kit is listed at USD 9.16.
Quick verdict
If you want the broader size selection, the 390pc kit is the practical pick. If you'd rather have the Ladinka kit, the 380PCS set is the one to reach for. The real difference is how you like to work: pick the 390pc for breadth, the Ladinka 380PCS for tidiness.

Where each product wins
The 380PCS kit wins for packaging and organization. It arrives pre-sorted in a compact case with easy-to-read labels, so you can quickly find the spring you need without turning your workspace into a spring collection. This is the kit to grab when you don't want tiny springs sliding around in a drawer.
The 390pc kit wins for total piece count and size coverage. It includes more springs and more size options, including 0.8mm springs, so it can handle a wider variety of repairs. This is the kit to reach for when a repair calls for a size you didn't plan on.
Product notes
380PCS Compression Spring Assortment Kit (Ladinka)

This Ladinka-branded kit bundles 380 stainless steel compression springs in 23 sizes from 0.3mm to 0.7mm. The pre-sorted case with easy-to-read labels is the standout feature here, making this set a strong choice for home repairs, crafts, and DIY projects where you want to grab the right size quickly. It also lists an MPN of DD-1 for reference. The labeled compartments are a small touch that makes a big difference when you're replacing a worn pen spring or fixing a measuring tape. Springs in this size range suit retractable pens, measuring tapes, door hinges, and screen door handles.
Choose this kit if you value organization and a named brand. The trade-off is that it stops at 23 sizes and 380 pieces, so if your projects routinely need larger springs or more variety, it may feel smaller than the 390pc alternative.
390pc Compression Spring Assortment Kit

This 390-piece assortment spans 28 sizes from 0.3mm to 0.8mm, making it the larger kit in this head-to-head. The 390 pieces and 28 sizes make it the more comprehensive option in this pairing. The listed compatible groove diameter is 2 millimeters with a round head style, which gives you a concrete spec to check against your spring seat. The item model number CSP-01-390 is listed for reference. The added 0.8mm sizes give you extra headroom for small repairs and craft projects. The kit uses a round head style and plain finish, matching common small-spring applications.
Choose this kit when the numbers matter most: more springs, more size options, and coverage that extends to 0.8mm springs. The limitation is that the 2-millimeter compatible groove diameter won't suit every application, so if your setup uses a different groove size, this assortment may not be the right fit.
Final choice by use case
If you're handling everyday repairs and want the widest size selection, the 390pc kit is the stronger buy. If you'd rather have the branded Ladinka kit, the 380PCS set is the pick. For a desk drawer, the Ladinka kit's tidy approach is hard to beat; for a full workshop, the 390pc kit's extra sizes may save you a second order.
