ORDERING & STORE POLICIES

What if I order several units of the same product? Will they arrive one by one or as a single delivery?

When you order multiple units of the same item, they arrive together (even if every unit is packed separately). So you won’t have to wait for multiple deliveries at different days!

Are your packages safe enough?

We use all the possible methods of securing your packages because it’s our greatest responsibility to protect them from damage.

Will the shipping time change depending on the payment option I use?

The payment method you choose won’t influence the order delivery time. So choose the method you find the most comfortable.

You can easily contact us through any of the contact channels listed at the bottom of the page. After that, we’ll reach out to you at short notice and answer all your questions.
