They fit perfect with the 2.5” x 2.5” labels from Avery, and I get the shipping boxes from Flush, they fit the jars phenomenally— https://flushpackaging.com/products/9-oz-straight-sided-glass-jar-shipping-box
Those are all Celestial Seasonings teas that I transferred from the original packages.
I bought the plain jars from Amazon: https://www.amazon.com/dp/B07PYLQZ6C/ref=cm_sw_r_apa_i_moBVEb26V5Y7F
Also the ribbons: https://www.amazon.com/dp/B07NHY6R61/ref=cm_sw_r_apa_i_mpBVEb6F20D3R
And bows: https://www.amazon.com/dp/B07Y13SR7Z/ref=cm_sw_r_apa_i_YpBVEb4KKM7D5
I just used a hot glue gun to attached the ribbons and bows to the lids of the jars.
