Evercare Fabric Shaver Large (2 Pack) https://www.amazon.com/dp/B00NFV1V9U/ref=cm_sw_r_cp_api_i_U5AjCb1MTEM3X

This is my favorite fabric shaver . Look for one that isn’t a two pack though unless you want two ... very powerful and I’ve tried like 4

StudioFX H9004SB2 2400 Watt Large Photography Softbox Continuous Photo Lighting Kit 16" x 24" + Boom Arm Hairlight with Sandbag H9004SB2 by Kaezi https://www.amazon.com/dp/B00MBVOIJU/ref=cm_sw_r_cp_api_i_C7AjCbHZ3QYDH

These are my exact lights but I got mine for $75 instead and my overhead light came broken so I never got to use it , but I think it would be great for flatlays . Definitely get four bulbs or more , the one bulbs suck. These aren’t high quality but they’re relatively cheap

10x13 Bags Poly Mailer Envelopes Bag (1000) Lets Go Shopping Pink Designer Fashion Poly Mailers Shipping Envelopes Boutique Custom Bags By ValueMailers … https://www.amazon.com/dp/B01M16WFZZ/ref=cm_sw_r_cp_api_i_w9AjCbJAV42QE

These are my polymailers , I only paid like 35 /1000 on eBay for them though . They’re pretty thin but I use Walmart bread bags to protect everything so it doesn’t matter to me . On Poshmark I usually just use the free boxes and I just learned about the tyvek which looks similar to a poly mailer that I’m gonna check out . I only use my poly bags if I’m being lazy af and don’t want to make a box

That’s about it ... you’ll of course want a measuring tape , apparently you want a good quality one so it doesn’t stretch ... I just checked all mine and they’re all off . Best bet would to at least get a hard hard stick

Oh and a fabric steamer , a good one is gonna cost a lot but I’ve been using this one for a bit and it was good until I broke it by leaving it in all night

If I had a lot like over 300 in amazon cards I would definitely try to get a good steamer ... it makes things so much easier (not as easy as just taking the clothes out of the dryer ASAP but who has time for that )

Also think about your printer . Mine sucks so I can’t suggest one , but I use toner which I still haven’t replaced in like 400+ labels now . Label specific printers are prob good but idk anything about them
