Probably one of the most obscure things to ask for, but I don’t want to resort to buying a full TE-S just for the casing just yet. so I’m scouting around, seeing if anyone has one for sale.
POST UPDATED FOR SALES:
Two darkhai & black Sanwa buttons, minimal wear. £5 shipped to the UK (maybe a bit more for the US because of shipping)

I do have some white sanwas aswell, but I’ll get pictures before posting up anything.
Next, balltops:

These have never been used because my impulse buyer senses were tingling at shiny things.
Seimitsu violet bubbleball: £5 Shipped to the UK
Sanwa Black meshball (NOT OG!): £7 shipped to the UK.
I can also haggle or trade. I am willing to trade a black meshball for a violet meshball and a violet bubbleball for a pink one.
