https://hidden-lab.com/page/thermochromic-keycap https://hidden-lab.com/new-arrivals/thermochromic-standard-set-cantaloupe#/31-switch_type-topre Switch Type: Topre Condition: brand new and sealed Colour: from orange to yellow (and back again when cooled) This keyset covers the HHKB arrow cluster, esc & fn, and WASD keys. Just got this in the mail today and hasn't been taken out of the packaging. Realised that the yellow is too light and doesn't match my other yellow artisans, so I don't really want this any more. My normal room temperature causes the colour to completely change to yellow way too easily so it's probably best to use this in air-con environments (around 25°C). Selling below retail price (60 USD) + shipping (5 USD), not that it's still in stock anyway.
Other possible locations are Bukit Timah or Serangoon (one per week).
