A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!
Guidelines:
Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!
Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.
Videos links are not allowed as post titles, but you may use them in a text post.
A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:
- The item must be made with sustainable or recycled materials.
- If electronic in some way, the item must be open-source.
- The item must be user-serviceable (if applicable).
- You cannot be a large corporation.
- The post must be clearly marked with a [Self Promotion] tag in your title.

MODERATORS
Any recs apart from nalgene as they are all ugly in my opinion
Personally I think you can go on aliexpress and buy any one of dozens of designs. They’re all made in China just white labelled.
If you like brands, zojirushi is quality. I hate the brand but yeti does have nice features on their bottles. Kleen kanteen also good. But they’re all pretty similar.
+1 on Zojirushi. They make excellent vacuum bottles and other related household/kitchen items and utensils. I’ve got one of their bottles and a water boiler.
Laken thermo bottle. Stainless steel. Keeps liquids cool/hot for ~4 hours. Built like a tank, it has gone flying from my backpack pocket multiple times - once it rolled on the ground for 50 meters when I had a bike accident. Still works after 10 years, using it daily.
Contigo are pretty good plastic ones that look a bit nicer. If you want metal, I have a few from Stanley that are great at keeping stuff iced for literal days, but they’ll obviously be heavier. They’re also more expensive too.
I have a metal, contigo one, works as intended
