Not the full list but this should get you started.

Recommend any old kitchen weight scale you can find. Silicone's are often measured out by weight so it's a must. Any kind will do.

https://www.amazon.com/dp/B07JBRD6BT Pipets, 300 worth for a good price.

https://www.amazon.com/dp/B08L7PP8F9/ A really nice starter kit with mixing cups, stir sticks, pipets and mini finger gloves.

https://www.amazon.com/dp/B01LYHYHEA California Air Tools CAT-1P1060S air compressor. You might be able to find it cheaper at Lowes, that's how I got mine.

https://www.amazon.com/dp/B001BHGC7G Zona papers for dice polishing

https://www.amazon.com/dp/B08HN5BNJD/ Mini pottery wheel for sanding/polishing. Trust me it will save your hands BUT browse around, this is a generic kind that people/brands can buy in bulk and sell under their listing, so you could find it cheaper elsewhere or with differing addons. Recommend getting some thin plexiglass sheets to glue on top to give you a flat smooth surface to polish on. The motor isn't strong but that's good as it avoids you pressing down too hard as it'll just stop it dead. snding/polishing only needs a light touch.

https://www.amazon.com/dp/B001NSCISK Air filters for respirator.

https://www.amazon.com/gp/product/B08PBJ8NDT/ Over sized silicone mat. Note look for other listings, some offer 2 for just a little more. Could also find some at slightly diff sizes for less.

Thing's to avoid and look out for: Many, MANY supplies listed on amazon (and other locations) for resin, rather molds, cups, pigments, decorations, glittewrs, etc etc are outsourced, meaning like with the pottery wheel, people/companies reach out to factories/producers and order items in bulk to then slap their own brand/label on it and market it for this or that to sell. Or mix and match them with other items. So ignore brand when looking up such things and go purely off price and what is offered. The items are all the same.

Same goes for thing's like Mica powders and other pigments. Just look for who offers the best color range and lowest price. While one brand might have colors another has 90% will end up being the same and a bit of a waste. They also badly photoshop product images so keep a mind of that.

Avoid at all costs ANY resin 'mixers' on amazon... They are all just milk frothers or other mixers for liquids and are not strong enough for resin.

Avoid alcohol inks. They are not designed for resin and often discolor but like said above, people will order them in bulk, slap their name on them and market how they want. Look instead for DYES but be mindful also that some sellers of alc inks have started labeling theirs as dyes.

Last for resin, really just go for whatever is cheapest on the market.

https://www.amazon.com/dp/B01LYK2NAG/ That is my normal go to but wait for the price to drop, it's normally around $50 for the gallon but when demand starts going up so too does the price.

https://www.amazon.com/dp/B099XFL1PK/ 2nd brand of resin I use and right now it's the lowest price as of writting this.

https://www.amazon.com/dp/B086JJMRG6 This brand is normally high cost but one thing it has over the rest is this is a very liquidy resin where as the others are thick. I use this for set designs that use a lot of inserts as the more liquid flow of it helps avoid trapped bubbles on items. It's also the only resin I would dare use (only on occasion) with out a mask due to its low order and fumes. However due to the cost naturally being so high it's only used for set projects and designs.

I always recommend people buy a quality airbrush. It will last a lifetime if you treat it reasonably well and prevents frustration. I would get a badger 105 and a compressor with a tank if I were trying to get the best bang for my buck. The 105 can be upgraded, repaired, and modified -- all the parts are extremely easy to get and they are built like trucks. If your kid wants a better airbrush down the line, I'm certain they will keep the 105 around for basecoating or spraying metallics.

I'd get these:

I went with a larger version of this this

It's insanely quiet. Your neighbors will thank you.

This is the one I went with since I have a diesel pusher and room wasn't really as much of an issue (plus I had it before I got the RV)

if you're worried about sound in your apartment, this compresser is very quiet but pricey. there are def cheaper options but they will be ~loud~
