Hello Shay, yes, if you order custom size (3 weeks processing time) now & use free shipping (20-30 days shipping time), it will reach you around mid-May, but we are unable to 100% guaranteed the exact delivered date; to be more safety, you can choose faster shipping method (except free shipping). n_n
*All shipping information (including methods, cost & estimated delivered date) will be shown in order page, before payment.
*Please remember to mark down the date (you need it) in the order form when you order it. :)
