Aquarium Gravel, 1-3cm, 4 boxes of 1kg each

Aquarium gravel. Stones are 1-3 cm in size.
Purchased from Amazon in April 2026, but I am listing them as I will not be using them.
Each box contains 1 kg, so there are 4 boxes totaling 4 kg.
The boxes have not been opened since purchase.
Therefore, the contents have not been checked.
Please understand this point.
The 4 boxes will be taped together and shipped.
