Every item designed is to be produced in a definite commercial lot just one time!
Every item has been being produced in a lot equal to 500-1000 pieces since 2017 and a collection consisting of 8-12 items is to be produced once a month.
The design sold can be repeated in 1-2 years, but on some other item.
If you would like to buy a T-shirt, don`t put that off for the next season: most probably it is to be sold this season and won`t be sold the next one!
