I think the rule of thumb should be if you can source it here, just avoid the potential hassle and loss of bringing anything beyond the essential. If you use any nutritional supplements then I’d say bring a supply of those to last an interim period. Same goes for any cosmetics, meds, and toiletries. Some items may be more difficult to obtain once here, but nothing is unobtainable, and you can always come to the forum and seek advice on particular items anyway.
Good luck on the jump!
