How big are Dish Sponges?
Retail 6-pack, compressed
118 × 78 × 14 mm (L × W × H). That is how the pack arrives, before any sponge has been wet.
Single sponge, hydrated
128 × 83 × 19 mm. Submerge the sponge or hold it under a running tap and it expands to full working size.
Why do they arrive so flat?
Compressed for transit
Shipping the sponges flat keeps packaging compact and cuts the volume moved per order. Nothing is missing from the pack.
It expands on contact with water
Hold the sponge under a running tap or submerge it and it reaches full working size. Flat and thin out of the pack is exactly what you should see.
