Natural Driftwood, Art and DIY Goods Large Driftwood Due to the storage period, there may be dust in the gaps. If you are concerned, please clean it before use. There are holes at both ends, so it can be used for various purposes such as hanging wood for flowers or a bird perch. I don't know if the astringency has been removed, so if you are using it for an aquarium, please handle it if necessary.
