Looking for new A4 loose pages

[MHBru]

I currently use 52gsm white TR paper.  For me it is too thin and flimsy.... and shows through more than i would prefer.  I love Clairefontaine Triomphe paper but it is too heavy for multi-page international letters.  So what's in between?  I prefer white that's able to show sheen and shading.  Blank, dot grid or lined works.  I look forward to your suggestions.  PS... I am in the USA so stuff I can get here, please..

For my international letters I use TR because it's better than airmail paper. I use regular dye based inks that don't show through at all and I always use both sides of my TR paper. I've received letters on onion skin paper bought on etsy or ebay If you can get Maruman Mnemosyne paper in the right size that's a great writing paper.

Amazon stocks a wide array of international papers. I have used Gohrsmuhle in an 80gsm formulation which is really nice. I don't use both sides, but looking at a current letter, it has some show through but no bleed with an Iroshizuku green ink in a Pelikan M1000 EF nib. Vanness has the Yamamoto papers as both a sampler and packs of 50 or 100 sheets, some of which are nice and light and A4 sized. Feel free to PM me if you have any questions.
