I purchased a set of 4 on Amazon. I opened one because my hands are small, but it was too big, so I am selling the remaining 3 unopened sponges. They are slightly larger than Sunsun sponges, and the foaming and water drainage are similar. Product Description: 【Compact Compressed Packaging】 The sponges are individually compressed, making them easy to store and space-saving. 【Durable and Long-lasting】 Made of flexible polyurethane, they are elastic and resistant to deformation even with daily use. They have a solid thickness and are durable even with repeated use. 【Excellent Foaming, Saves Detergent】 The fine bubbles in the sponge hold foam well, creating a rich lather even with a small amount of detergent. This reduces detergent usage, allowing for smooth cleaning, which is economical and environmentally friendly. 【Density Design for Good Water Drainage】 The sponge drains water well and dries quickly after use. This prevents slime and mold, keeping it hygienic. 【Abrasive-Free】 Designed to be gentle on delicate dishes such as coated frying pans, pots, and glassware. Kitchen Sponge, Dishwashing Sponge, Durable
