I think they just have fewer in a package.
What do I use as a picker some may ask. Well Beak has some bullshit for the masses. stainless steel has the least deflection. Then it comes down to thickness and ergonomics. There is a lot there to discuss. Softer options are slick cellulite, or soft torex if you like metal picks, you'd gravitate towards the softer metals than stainless, like zinc or nickel. Don't leave out the ergonomics, like a depression for your thumb and forefinger tip. Sand paper. Grip tape. Printed or pressed grooves for stability and tight gripping control. Stylus? forgetaboutit. Pick technology has come a long way. $45 bones don't scare me.
