How long will durable last after its expiration date?
its in a completely unopened package?
I have had some for nearly a year that was unopened. I used it recently without any major issue. I did shake it up once a month or so - I do not know if this is necessary or not, read somewhere that was a good idea. I did have to clean some thickened material from the spout area in order to get it to dispense properly once in my printer.
Hi @jcamper ,
Thanks for reaching out! According to our Choosing The Right Material page, it appears Durable has a shelf-life of about 24 months. There is a lot number sticker on the underside of each cartridge that has an expiry date listed as well. Please let us know if you have other questions or concerns!
