oh! i sorta got in to the hole collecting of erasers, i dont really collect Gomus but i collect ones from Smiggle-

they like have thousands of modles of erasers and new ones come out every month or so, and they cost about a dollar each-ish

i dont use mine eather or then i'll go back to the shop and buy more

BTW, Smiggle is a shop that sells all sorts of stationary that have different designs they dont only sell stationary they also sell stuff like smigglised phone covers, bags, drinkbottles,wraping paper and even smiggle playing cards o_0 omg. and there collectable since most designs only stay out for 3 months.
