Hello, Na-hye Kim :)

The textbooks currently used offline are not publicly sold or provided because their content is modified whenever the CAD version is updated.

Please leave your email address in the inquiry or contact us via KakaoTalk Channel 'UTTUIf you request it along with your email address, we will send you a PDF file for reference.

In addition, the items listed as "textbook patterns" on the pattern market are pattern books available for purchase in stores or textbooks used in universities.

Please note that we are unable to provide this information as we do not have the data, as it is not a pattern product offered by us.

Thank you for your interest :)
