I have some stuff I won't be using anytime soon, so I'm trying to get rid of it.
1) Set of 63 Hypersphere silencing rings. This set is for a HHKB Pro 2 (with 3 rings to spare). Price: 35 EUR.
2) Hasu BT module. Currently loaded with QMK software which allows the keyboard to be used with an iPad or an iPhone. Battery not included. Price: 60 EUR. SOLD
I'm in Europe, so here's an opportunity for another European citizen to save some money (I pad import tax for the silencing rings). The prices exclude shipping costs. You'll have to tell me where you are located, in order for me to calculate how much it'll cost to ship to you.
