Yes.

• 3h2) Puzzles whose coloured plastic is visible inside the puzzle (e.g. "stickerless" puzzles) are permitted.

• 3h2+) CLARIFICATION In the past, "stickerless" puzzles were not permitted. Such puzzles are now permitted.

So long as the puzzle follows:

• 3j3) Corrugated/textured parts which permit the orientation of pieces to be distinguished by feel are not permitted for blindfolded events.
• 3l2) The logo may be embossed, engraved, or consist of an overlay sticker. Exception: The logo must not be distinguishable by feel for blindfolded events (i.e. no embossings, engravings, or overlay stickers).
