Wahl Clipper Genuine Secure-Fit™ Attachment Guard Organization Kit with Color Pro Colored Hair Clipper Guide Combs, 14 Piece Premium Storage Kit Hair Clippers, Multicolor - 3291-100

I too tried to design a few clipper guards but grew frustrated with the time and results. Defeatedly, I ordered the Wahl set from Amazon and I'm glad I did. Very high quality guards with every size! https://www.amazon.com/dp/B09XLWXKVV?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
