Czech splatter???? Any ideas

Different colors same shape!!!! A white base color with splatter on it and cased in clear. The multi-colored one is more appealing to me. Stand at 6" tall .,the opening is 1 7/8 " and the base is 2 3/8". Any ideas who to attribute these to to...or maybe?????? An update to this post, the vase on the left is stamped "Made in Japan". When I found it, I liked the shape and it was sitting with many other Czech pieces.... then turned it over and saw the stamp. I put it down and bought other pieces. A couple days later I went back and bought it to have it as an example..... since then I found the other one to place next to it. When sitting next to other splatter pieces of Czech...…there is a definite quality difference!!!! Czech is the BEST!!!!!!!!!! Artfoot and Welzbub knew immediate!!!!!!!!
