【Package Content】 The package includes 20 pieces of soldering iron cleaning sponges. Each sponge expands to approximately 3.5 × 5 cm after soaking, with a thicker design compared with many standard soldering sponges on the market, providing better cleaning performance and longer service life. 【High-Quality Wood Pulp Fiber Material】 Made of premium wood pulp fiber, these soldering tip cleaning sponges feature excellent water absorption and strong cleaning ability. They effectively help remove solder residue and keep soldering iron tips clean for better maintenance. 【Quick Expansion Design】 Simply place the dry sponge into water, and it will quickly absorb water and expand to its full size.
