Well, you can also improve the quality of the packaging. Resin is quite expensive. If you can’t catch up on how to avoid leakage, put a bag on the lids of two formulations, and wrap your throat with masking tape. (Like paint when you take it on tap) Sent for my husband's order. I would probably return it myself. For masters, every drop counts. Not much has flowed, but at least it is not safe. Resin is harmful. I ordered this resin to try for the first time. I'll try to supplement the review on the resin itself
