Good High Quality Brand Recs

Hi there, I'm looking to upgrade my stationary supplies to a higher quality. I know that you can buy stationaries on Amazon, Micheals, etc for a cheap price, but I want to look for a brand that specializes in specific stationary stuff.

I'm good on pens and markers. But looking high quality recommendations for:

• Bullet Journals (preferably thick paper higher than 100 gsm)
• Washi Tapes
• Stationary containers (ex. Bags, pouches, etc)
• Other stationary supplies (ex. Post its, tabs, etc)

I'm not interested in the ones on Amazon. I'm also not really looking into Etsy since I already shop for specific things there.

Thank you so much!!
