Business
Quantum Apothecary, operated by Tonic Thought Studios
Mailing address
4140 Minnehaha Avenue
Minneapolis, MN 55406
United States
This is a mailing address, not a shop and not a returns address. Do not ship anything here without emailing first — returns are handled through our production partner, not through this address, and an unannounced parcel will not resolve your claim.
tonicthoughtstudios@gmail.com
This is the reliable route for everything: order questions, sizing, damage claims, shipping problems, wholesale, and data requests. Put your order number in the subject line if you have one.
Response time
We answer within 2 to 3 business days. Weekends and US holidays are not business days. If something is time-sensitive — a wrong address on a fresh order, for instance — say so in the subject line and we will get to it sooner.
