It's London プランナーステッカー

The little London landmarks are so detailed—the vinyl feels sturdy and the sheet is packed with 26 designs, so I've already covered two months of spreads. I peeled one off and restuck it without any curling or residue, which never happens with my old sticker sets.

The repositionable stickers are a game-changer for when I mess up my layout—peel and stick again without any damage. The illustrations have a charming, hand-drawn feel that makes my planner look unique.

The waterproof vinyl is a lifesaver for my water bottle—they've stayed put through multiple washes. Each sheet has a good mix of sizes that fit perfectly in my hourly planner slots.
