Polybius: Insert Coin T-Shirt

Why It’s Your New Favorite ❤️

• Ridiculously soft — made from smooth, combed cotton that feels broken-in from day one. 
• Lightweight but not flimsy — perfect for year-round wear, with enough structure to keep its shape.
• True-to-size fit — modern cut that works for all genders. Not boxy, not skin-tight, just right.
• Holds up wash after wash — no twisting seams or bacon-neck.

How to Care for Your Tee

Want your favorite retro tee to last through a hundred wash cycles and still look good? It’s easy:

• Wash cold, inside out, gentle cycle
• Tumble dry low—or better yet, hang it like it's 1995
• No bleach, no ironing the print, no weird experimental laundry hacks

Treat it right, and your shirt will stay soft, vibrant, and ready for whatever nostalgia trip comes next.
