- they all came funded with 0.25 XMR. it is still funded, unless the hologram was peeled and the private key retrived.
- a refunding or similar was never offered and will never be offered.
- few cards still available, that is correct. See for numbers: https://bitcointalksearch.org/topic/wts-funded-025-xmr-monero-collectible-giftcard-feat-moonbits-22128-left-5140464
- the funding was done by MoonBits. I never touched, saw or in any other way interacted with the private keys. MoonBits is and will always stand for top-security and quality privatekey handling, I know them personally and have the highest level of trust for them.
