Unfortunately, we are unable to offer the desired spare part through us. Spare parts are generally not intended for resale, but are primarily provided to service centres for repairs. For this reason, we do not have any corresponding sources of supply. I would highly recommend that you contact the manufacturer directly: https://ch.alessi.com/de...
