If you are looking to pre-order a decorated 3D cake from an online store, you may be able to find the pre-order time information on the product page. It's important to note that these types of orders are typically taken on a first-come, first-serve basis, so it's recommended that you place your order in advance to ensure availability.

In particular, fondant cake orders and custom cake orders often require a few days in advance to prepare. Depending on the complexity of the design, it may take even longer to create a custom cake. For this reason, it's recommended to place orders more than a week or a month in advance or even earlier if possible. By doing so, you can ensure that your order can be accommodated and that it meets your specifications.

It's important to carefully review the pre-order information provided by the online store and to plan accordingly to avoid disappointment. By placing your order in advance and understanding the time requirements for your specific cake, you can ensure a successful and enjoyable experience.
