Do you also want to make the most sustainable Christmas piece possible? That’s possible, because we have finally found a sustainable alternative to Oase or floral foam: Sideau. Oh how happy we are about this because unlike floral foam, which is made from oil derivatives and phenolic resin – which is plastic – Sideau is 100% completely biodegradable. View all the benefits of Sideau in our webshop via this link. Of course, we also have these blocks in the store, so you can immediately take a nicely filled Christmas bag with you.
