For the phonetic reading blocks, these are better in all aspects: https://www.amazon.com/Little-Bud-Kids-Montessori-Flashcard/dp/B085X93ZJN/ref=sr_1_4?dchild=1&keywords=reading+blocks&qid=1602660209&sr=8-4

I got this set and it comes with 30 double-sided flashcards on a ring which work really well for my daughter to self-correct and learn on the go. The tote bag and product box is also really nice.
