Our system includes the possibility of canceling your order up to 24 hours before the event. In order to inform our customers of this operation, we have included a special mention on this subject in the reservation process. When ordering, you checked the validation box for this mention.
Once the 24-hour period before the event has passed, whether you attend the party or not, the pre-sale is final and can no longer be refunded.
All cancellation, modification and refund terms appear in our general conditions of sale and use
