I don't currently have any sculpted boop! caps but I do have blanks in every stem type she makes. Figured I'd do a sort of review to give everyone some idea how they'll fit.
Topre deep purple esc (might be slightly metallic), very dark metallic purple MX esc (not grey like it appears), bright pink Alps fn.
The stems. MX is a bit tight but this is a prototype and it's been fixed on the new caps. The Topre stem is a 2 piece but it feel much more solid that other 2 piece stem Topre artisans I have, also has the classic Topre click when you put it on. Finally the Alps fn, which has the best Alps stem I've seen on an artisan. Usually Alps stems are too loose and pop off or too tight and terrifying to remove but this cap fits right into the middle, it holds solid but I'm not scared I'll break it when taking it off.
Bonus shot of the Topre mod, same stem as the esc.
