If your luggage wheels are broken or worn out, this Bstinay replacement wheel kit is exactly what you need to bring your favorite suitcase back to life! You get 4 swivel casters (2 pairs) that are designed to replace most standard luggage wheels. The W187 model has specific dimensions: total length 8.3cm, wheel diameter 5.2cm, wheel width 1.6cm, with hole spacing of 2.9cm/3.5cm/3.5cm/2.9cm - be sure to measure your existing wheels to ensure compatibility. The PVC and metal construction provides good durability, wear resistance, and a quiet, smooth roll. The kit includes everything you need for installation: 16 screws, 2 dual-purpose screwdrivers (for different screw head types), plus some bonus travel accessories like face oil blotting sheets, multicolor rubber bands, and double-pointed swabs. The replacement process is straightforward DIY - just remove the old wheels and screw the new ones into place. This can save you the cost of buying new luggage or expensive repair shop fees. The wheels have good flexibility and mute effect, meaning they roll quietly without that annoying clacking sound some cheap replacements make. Before purchasing, carefully compare the hole arrangement and measurements with your existing wheels to ensure perfect fit. With proper installation, these replacement wheels can make your luggage feel like new again and save you from having to replace your entire suitcase!
