Guys I need a bit of advice, I have seen a guy offering to sell a clean Mr Fuzzy outfit. I was thinking of buying it, the price is reasonable but my only reservation is that when I googled it I found mixed results. Is it a glitched item or a dev item or is it legit ? Will it get removed from my inventory by Bethesda eventually if I buy it ?
Thankyou in advance for your help
